Optical lens, camera module and electronic equipment
Technical Field
The present invention relates to the field of optical imaging technologies, and in particular, to an optical lens, a camera module, and an electronic device.
Background
In recent years, with the update of portable electronic devices such as smartphones and tablet computers, imaging modules mounted on portable electronic devices have been challenged. On the one hand, portable electronic devices show a trend of light and thin, which makes the optical lens further compressed in axial dimension; on the other hand, it is also necessary to ensure that the optical lens satisfies the miniaturization design while giving consideration to higher imaging quality. Therefore, how to make an optical lens achieve a miniaturized design while maintaining good imaging quality by configuring the number of lenses, refractive power, surface shape, etc. in the optical lens is still a technical problem that needs to be solved in the field of optical imaging technology.
Disclosure of Invention
The embodiment of the invention discloses an optical lens, an image pickup module and electronic equipment, which can realize the characteristics of high resolution and high imaging definition while realizing the miniaturization design of the optical lens, and realize the Gao Qingcheng image requirement of the optical lens.
In order to achieve the above object, in a first aspect, the present invention discloses an optical lens having eight lenses in total, the eight lenses being a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens in order from an object side to an image side along an optical axis;
the first lens element with positive refractive power has a convex object-side surface at a paraxial region and a concave image-side surface at a paraxial region;
the second lens element with positive refractive power has a convex object-side surface at a paraxial region;
the third lens element with negative refractive power has a convex object-side surface at a paraxial region and a concave image-side surface at a paraxial region;
the fourth lens element with refractive power;
the fifth lens element with refractive power has a convex object-side surface at a paraxial region;
The sixth lens element with positive refractive power has a convex object-side surface at a paraxial region and a concave image-side surface at a paraxial region;
the seventh lens element with positive refractive power has a convex object-side surface at a paraxial region;
the eighth lens element with negative refractive power has a concave object-side surface at a paraxial region and a concave image-side surface at a paraxial region.
In the optical lens provided by the application, the first lens has stronger positive refractive power, the side face of the collocation object is convex at the optical axis and the side face of the collocation object is concave at the paraxial region, so that the space of the optical lens can be effectively utilized, the light, thin and small-sized optical lens can be realized, and meanwhile, the first lens is favorable for ensuring that the first lens has enough light converging capability; the convex design of the positive refractive power and the object side surface of the second lens element at the paraxial region can assist the first lens element to converge light rays, which is beneficial to correcting partial aberration generated by the first lens element; the positive refractive power provided by the third lens element and the convex-concave surface design of the object-side surface and the image-side surface thereof at a paraxial region thereof can counteract aberration generated by the positive and negative lens elements, so that marginal field aberration generated by the first lens element and the second lens element can be effectively corrected. The convex surface design of the object side surface of the fifth lens element at the paraxial region can further collect light rays, and is favorable for compressing the total optical length of the optical lens. The positive refractive power provided by the sixth lens element matches the convex-concave surface design of the object-side surface and the image-side surface at the paraxial region, which is beneficial to correcting the curvature of field of the optical lens element and improving the optical performance of the optical lens element. The seventh lens element has a convex surface configuration with a positive refractive power disposed at a paraxial region, which is beneficial to correcting aberrations generated from the first lens element to the sixth lens element, ensuring aberration balance of the optical lens element, and improving imaging quality of the optical lens element. The negative refractive power and the concave surface design of the object side surface and the image side surface at the paraxial region provided by the eighth lens element, so that the eighth lens element has a distorted surface shape, which is beneficial to ensuring the imaging quality of the central view field by effectively correcting the aberration such as astigmatic aberration and the like, and meanwhile, the situation that the surface shape is too distorted to be processed and molded can be avoided.
As an alternative implementation manner, in an embodiment of the first aspect of the present invention, the optical lens satisfies the following relation:
TTL/ImgH＜1.35；
wherein TTL is the distance between the object side surface of the first lens and the imaging surface of the optical lens on the optical axis, that is, the total optical length of the optical lens, and ImgH is the radius of the maximum effective imaging circle on the imaging surface of the optical lens, that is, the half image height of the optical lens.
The ratio of the total optical length to the half image height of the optical lens is controlled within a reasonable range, so that the size of the optical lens can be effectively controlled on the premise that the optical lens has a larger image plane, the structure of the optical lens is more compact, the optical lens has ultrathin characteristics, the miniaturization design requirement is met, the optical lens can be better carried on the light and thin electronic equipment, and meanwhile, the optical lens can be compatible with a large-size photosensitive chip, so that the imaging quality of the electronic equipment is improved. When the upper limit of the above conditional expression is exceeded, the total optical length of the optical lens is too large, which results in an increase in the thickness of the optical lens in the optical axis direction, which is unfavorable for the light, thin and miniaturized design of the optical lens.
As an alternative implementation manner, in an embodiment of the first aspect of the present invention, the optical lens satisfies the following relation: 0.78< f1/f2<1.02; wherein f1 is the focal length of the first lens, and f2 is the focal length of the second lens.
The first lens element with positive refractive power provides a portion of positive refractive power, and the second lens element with positive refractive power further converges light rays. When the above conditional expression is satisfied, the refractive powers of the first lens element and the second lens element can be reasonably configured, which is beneficial to reducing the focal length of the optical lens element, thereby being beneficial to further reducing the thickness and weight of the optical lens element. Meanwhile, larger spherical aberration generated by the first lens and the second lens can be balanced, the configuration of the refractive power of the rear end of the optical lens is controlled, the correction of peripheral aberration of the optical lens is enhanced, good correction of aberration and curvature of field of the whole optical lens is carried out, and the overall resolution of the optical lens is improved. When the upper limit of the above conditional expression is exceeded, the focal length of the first lens element is too large, which results in too weak refractive power, which is not beneficial to the first lens element to collect the light from the object side, and is not beneficial to the light with a large angle to enter the optical lens element, so that the light flux is reduced, the field of view of the optical lens element is reduced, and the shooting requirement is difficult to meet. When the focal length of the first lens element is smaller than the lower limit of the above-mentioned relation, the refractive power of the first lens element is too high, which not only increases the sensitivity of the optical lens element and makes the processing technique difficult, but also increases the difficulty of correcting the aberration generated by the first lens element and reduces the imaging quality.
As an alternative implementation manner, in an embodiment of the first aspect of the present invention, the optical lens satisfies the following relation: 2.5< R9/f <8.3; wherein R9 is a radius of curvature of the object side surface of the fifth lens element at the optical axis, and f is a focal length of the optical lens assembly.
When the above conditional expression is satisfied, the convex surface design of the object side surface of the fifth lens element at the paraxial region is matched, so that the light rays can be further converged, and the focal length of the optical lens can be controlled within a reasonable range, thereby being beneficial to compressing the total optical length of the optical lens, and enabling the optical lens to satisfy the design requirements of lightness, thinness and miniaturization. When the upper limit of the above conditional expression is exceeded, the radius of curvature of the object-side surface of the fifth lens element is larger, and the refractive power of the fifth lens element is weakened, so that the focal length of the fifth lens element is increased, which is disadvantageous for shortening the total optical length of the optical lens element; when the refractive index of the object-side surface of the fifth lens element is smaller than the lower limit of the above-described conditional expression, the refractive power of the fifth lens element increases, which results in a smaller focal length of the fifth lens element, and the sixth lens element, the seventh lens element, and the eighth lens element are liable to increase the burden of correcting aberrations, thereby affecting the imaging quality.
As an alternative implementation manner, in an embodiment of the first aspect of the present invention, the optical lens satisfies the following relation: i f1/f8 <2.6; wherein f1 is the focal length of the first lens, and f8 is the focal length of the eighth lens.
When the above conditional expression is satisfied, the focal length of the first lens can be controlled in a proper range, so that the focal length of the whole optical lens can be controlled, and the total optical length of the optical lens can be compressed, so that the optical lens meets the design requirements of lightness, thinness and miniaturization. When the upper limit of the above condition is exceeded, the absolute value of the focal length of the first lens element is too large, which results in a decrease in refractive power of the first lens element, which is not beneficial to compressing the total optical length of the optical lens element, and thus is not beneficial to the light, thin and miniaturized design of the optical lens element, or the absolute value of the focal length of the eighth lens element is too small, which is easy to increase the burden of correcting field curvature and astigmatism of the eighth lens element, and thus affects the imaging quality of the optical lens element.
As an alternative implementation manner, in an embodiment of the first aspect of the present invention, the optical lens satisfies the following relation: 1.8< R15/f8<2.1; wherein R15 is a radius of curvature of the object side surface of the eighth lens element at the optical axis, and f8 is a focal length of the eighth lens element.
By satisfying the above conditional expression, the negative refractive power provided by the eighth lens element can be controlled within a reasonable range, which is favorable for correcting the curvature of field, astigmatism and distortion of the optical lens element, thereby ensuring the imaging quality of the optical lens element. When the upper limit of the above condition is exceeded, the radius of curvature of the object side surface of the eighth lens element is larger, so that the back focal length of the optical lens element is difficult to shorten, and the overall volume of the optical lens element is larger; when the curvature radius of the object side surface of the eighth lens element is smaller than the lower limit of the above conditional expression, it is difficult to sufficiently correct the curvature of field and aberration of the optical lens element.
As an alternative implementation manner, in an embodiment of the first aspect of the present invention, the optical lens satisfies the following relation: 1< |SAG82/CT8| <2.2; the SAG82 is a sagittal height of the image side surface of the eighth lens at the maximum effective radius, that is, the SAG82 is a distance from the maximum effective caliber of the image side surface of the eighth lens to a point of intersection of the image side surface of the eighth lens with the optical axis in a direction parallel to the optical axis, a direction from the object side surface of the first lens to the image side surface of the eighth lens is a positive direction of the optical axis, when the SAG82 value is negative, the SAG82 value indicates that the maximum effective caliber of the image side surface of the eighth lens is located at the left side of the point of intersection of the image side surface of the eighth lens with the optical axis, and when the SAG82 value is positive, the SAG82 value indicates that the maximum effective caliber of the image side surface of the eighth lens is located at the right side of the point of intersection of the image side surface of the eighth lens with the optical axis, and the CT8 is a thickness of the eighth lens on the optical axis.
The ratio of the sagittal height of the image side surface of the eighth lens at the maximum effective radius to the central thickness of the eighth lens is reasonably restrained, so that the relative illumination of the edge of the imaging surface of the optical lens is ensured, the risk of occurrence of a dark angle is reduced, the aberration of the optical lens can be effectively corrected, the imaging quality of the optical lens is improved, the sagittal height of the image side surface of the eighth lens at the maximum effective radius and the central thickness of the eighth lens can be restrained within a reasonable range, the surface shape of the eighth lens is prevented from being excessively distorted, the surface shape of the eighth lens is controlled within a range easy to process and form, and the processing and forming of the eighth lens are facilitated. When the upper limit of the condition is exceeded, the sagittal height of the image side surface of the eighth lens at the maximum effective radius is too large, so that the surface shape of the eighth lens is too distorted, the lens assembly difficulty of the optical lens is increased, and the chief ray angle of the optical lens is difficult to match with the chief ray angle of the photosensitive chip, thereby being unfavorable for improving the imaging quality of the optical lens; when the refractive index is lower than the lower limit of the above condition, the sagittal height of the image side surface of the eighth lens element at the maximum effective aperture is smaller, so that the high-order aberration of the off-axis field of view is difficult to be effectively balanced, the deflection angle of the marginal light incident on the eighth lens element is too large, the tolerance sensitivity of the lens element is increased, and the assembly of the lens element is not facilitated.
As an alternative implementation manner, in an embodiment of the first aspect of the present invention, the optical lens satisfies the following relation: 1.6< |r4/f2| <9.3; wherein R4 is a radius of curvature of the image side surface of the second lens element at the optical axis, and f2 is a focal length of the second lens element.
When the above conditional expression is satisfied, the second lens element has positive refractive power, and the radius of curvature of the image-side surface of the second lens element at the optical axis can be reasonably controlled, so as to share a part of the positive refractive power by matching with the first lens element, thereby improving the light converging capability of the optical lens element, shortening the total optical length of the optical lens element, and realizing the light, thin and compact optical lens element. When the upper limit of the above conditional expression is exceeded, the absolute value of the curvature radius of the image side surface of the second lens element at the optical axis is large, so that the surface shape of the second lens element is too gentle, and it is difficult to sufficiently correct astigmatism and distortion; when the absolute value of the curvature radius of the image side surface of the second lens element at the optical axis is too small, the curvature of the surface of the second lens element is too large, and the third lens element is burdened with correcting coma aberration.
As an alternative implementation manner, in an embodiment of the first aspect of the present invention, the optical lens satisfies the following relation:
-6< (f6+f7)/f8 < -5; wherein f6 is the focal length of the sixth lens, f7 is the focal length of the seventh lens, and f8 is the focal length of the eighth lens.
When the above conditional expression is satisfied, the total length of the optical lens can be further shortened by matching the positive refractive power provided by the sixth lens element and the seventh lens element, so that the optical lens can satisfy the light, thin and miniaturized design requirements. When the upper limit of the conditional expression is exceeded, the focal length of the seventh lens of the sixth lens is too small, so that the positive refractive powers of the sixth lens and the seventh lens are too strong, and the burden of correcting aberration of the eighth lens is excessively increased, which is not beneficial to improving the imaging quality; when the focal length of the seventh lens element is smaller than the lower limit of the above-mentioned conditional expression, the positive refractive power of the sixth lens element and the seventh lens element is too large, which is disadvantageous for the total optical length of the compact optical lens, and thus is disadvantageous for the light and thin and compact design of the lens.
As an alternative implementation manner, in an embodiment of the first aspect of the present invention, the optical lens satisfies the following relation:
5.3mm < f tan (HFOV) <5.5mm; where f is the focal length of the optical lens and HFOV is half the maximum field angle of the optical lens.
When the limitation of the conditional expression is satisfied, the deflection angle of the incident light in the optical lens is reduced, so that the surface shape of each lens in the optical lens is not excessively bent or gentle, and the manufacturing and processing of each lens are facilitated. In addition, when the optical lens meets the above condition, the angle of view and the image height of the optical lens can be reasonably configured, and on one hand, the axial dimension of the optical lens can be further compressed; on the other hand, the optical lens can have the characteristic of a large image surface, so that when the optical lens is applied to the image pickup module, the optical lens can be matched with a large-size photosensitive chip of the image pickup module, and the imaging quality of the optical lens is further improved. When the upper limit of the conditional expression is exceeded, the focal length of the optical lens is too long, so that the optical total length of the optical lens is difficult to compress, the volume of the optical lens is increased, and the optical lens is not beneficial to meeting the miniaturization design requirement. When the imaging information of the optical lens is insufficient, the imaging quality of the optical lens is affected.
As an alternative implementation manner, in an embodiment of the first aspect of the present invention, the optical lens satisfies the following relation: 1.4< R12/f <1.7; wherein R12 is a radius of curvature of the image side surface of the sixth lens element at the optical axis, and f is a focal length of the optical lens element.
By satisfying the above-described relational expression, the curvature radius of the image side surface of the sixth lens element at the optical axis can be controlled within a reasonable range, and astigmatism, curvature of field, and distortion can be corrected well. When the curvature radius of the image side surface of the sixth lens is smaller than the lower limit of the condition, the curvature of the image side surface of the sixth lens is overlarge, so that the sensitivity of the sixth lens is increased, and the engineering manufacture of the sixth lens is not facilitated; when the upper limit of the above conditional expression is exceeded, the curvature radius of the image side surface of the sixth lens element at the optical axis is large, resulting in excessively gentle surface shape of the sixth lens element, which makes it difficult to sufficiently correct astigmatism, field curvature, and distortion.
As an alternative implementation manner, in an embodiment of the first aspect of the present invention, the optical lens satisfies the following relation: 1< f6/f7<1.4; wherein f6 is the focal length of the sixth lens, and f7 is the focal length of the seventh lens.
Because the sixth lens and the seventh lens can provide positive refractive power, the focal length ratio of the sixth lens and the seventh lens is controlled within the range, so that the sixth lens and the seventh lens can reasonably share the refractive power, the spherical aberration contribution of the sixth lens and the seventh lens is kept within a reasonable range, the imaging quality of a field area of the optical lens on an optical axis is improved, and an effective pixel area on an imaging surface of the optical lens has good imaging quality; meanwhile, the optical total length of the optical lens is further shortened, so that the miniaturization design of the optical lens is met.
In a second aspect, the present invention discloses an image capturing module, where the image capturing module includes a photosensitive chip and the optical lens described in the first aspect, and the photosensitive chip is disposed on an image side of the optical lens. The camera module with the optical lens can realize miniaturized design and simultaneously has the characteristics of high resolution and high imaging definition, thereby realizing Gao Qingcheng image requirements of the optical lens.
In a third aspect, the invention also discloses an electronic device, which comprises a housing and the camera module set in the second aspect, wherein the camera module set is arranged in the housing. The electronic equipment with the camera module can enable the optical lens to have the characteristics of high resolution and high imaging definition while realizing miniaturization design, and can realize Gao Qingcheng image requirements of the optical lens.
Compared with the prior art, the invention has the beneficial effects that:
the optical lens, the camera module and the electronic equipment provided by the embodiment of the invention adopt eight lenses, and have reasonable number of lenses, ingenious structure and smaller volume. The first lens element with high positive refractive power has a convex object-side surface at the optical axis and a concave image-side surface at the paraxial region, so that the space of the optical lens can be effectively utilized to realize the light, thin and small size of the optical lens, and the first lens element can be ensured to have sufficient light converging capability; the convex design of the positive refractive power and the object side surface of the second lens element at the paraxial region can assist the first lens element to converge light rays, which is beneficial to correcting partial aberration generated by the first lens element; the positive refractive power provided by the third lens element and the convex-concave surface design of the object-side surface and the image-side surface thereof at a paraxial region thereof can counteract aberration generated by the positive and negative lens elements, so that marginal field aberration generated by the first lens element and the second lens element can be effectively corrected. The convex surface design of the object side surface of the fifth lens element at the paraxial region can further collect light rays, and is favorable for compressing the total optical length of the optical lens. The positive refractive power provided by the sixth lens element matches the convex-concave surface design of the object-side surface and the image-side surface at the paraxial region, which is beneficial to correcting the curvature of field of the optical lens element and improving the optical performance of the optical lens element. The seventh lens element has a convex surface configuration with a positive refractive power disposed at a paraxial region, which is beneficial to correcting aberrations generated from the first lens element to the sixth lens element, ensuring aberration balance of the optical lens element, and improving imaging quality of the optical lens element. The negative refractive power and the concave surface design of the object side surface and the image side surface at the paraxial region provided by the eighth lens element, so that the eighth lens element has a distorted surface shape, which is beneficial to ensuring the imaging quality of the central view field by effectively correcting the aberration such as astigmatic aberration and the like, and meanwhile, the situation that the surface shape is too distorted to be processed and molded can be avoided.

Further, the object-side surface S1 of the first lens element L1 can be convex at the paraxial region O, and the image-side surface S2 of the first lens element L1 can be concave at the paraxial region O; the object-side surface S3 of the second lens element L2 can be convex at a paraxial region O, and the image-side surface S4 of the second lens element L2 can be concave or convex at the paraxial region O; the object-side surface S5 of the third lens element L3 can be convex at the paraxial region O, and the image-side surface S6 of the third lens element L3 can be concave at the paraxial region O; the object-side surface S7 of the fourth lens element L4 can be convex or concave at the paraxial region O, and the image-side surface S8 of the fourth lens element L4 can be convex or concave at the paraxial region O; the object-side surface S9 of the fifth lens element L5 can be convex at the paraxial region O, and the image-side surface S10 of the fifth lens element L5 can be convex or concave at the paraxial region O; the object-side surface S11 of the sixth lens element L6 can be convex at the paraxial region O, and the image-side surface S12 of the sixth lens element L6 can be concave at the paraxial region O; the object-side surface S13 of the seventh lens element L7 can be convex at the paraxial region O, and the image-side surface S14 of the seventh lens element L7 can be concave or convex at the paraxial region O; the object-side surface S15 of the eighth lens element L8 can be concave at the paraxial region O, and the image-side surface S16 of the eighth lens element L8 can be concave at the paraxial region O.
Considering that the optical lens 100 is mostly applied to electronic devices such as mobile phones, tablet computers, smart watches, etc., the materials of the first lens L1, the second lens L2, the third lens L3, the fourth lens L4, the fifth lens L5, the sixth lens L6, the seventh lens L7 and the eighth lens L8 may be plastics, so that the optical lens 100 has good optical effects, and meanwhile, the overall weight of the optical lens 100 may be reduced, and the optical lens 100 may have good portability and may be easier to process complex surfaces of lenses. Meanwhile, the first lens L1, the second lens L2, the third lens L3, the fourth lens L4, the fifth lens L5, the sixth lens L6, the seventh lens L7 and the eighth lens L8 may be aspheric.
In some embodiments, the optical lens 100 further includes a diaphragm 102, and the diaphragm 102 may be an aperture diaphragm or a field diaphragm, which may be disposed between the object side of the optical lens 100 and the object side S1 of the first lens L1. It is to be understood that in other embodiments, the diaphragm 102 may be disposed between two adjacent lenses, for example, between the second lens L2 and the third lens L3, and the arrangement is adjusted according to the actual situation, which is not particularly limited in this embodiment.
In some embodiments, the optical lens 100 further includes an optical filter L9, for example, an infrared optical filter, which may be disposed between the image side surface S16 of the eighth lens L8 and the imaging surface 101 of the optical lens 100, so that light rays in other wavebands, such as visible light, can be filtered out, and only infrared light can pass through the optical filter, so that the imaging quality is improved by filtering light rays in other wavebands, such as visible light, and the imaging is more in accordance with the visual experience of human eyes; the optical lens 100 may be used as an infrared optical lens, that is, the optical lens 100 may be used to image in dim environments and other special application scenes and obtain better image effects. It can be appreciated that the optical filter L9 may be made of an optical glass coating film, or may be made of a colored glass, or may be made of another material, and may be selected according to actual needs, which is not specifically limited in this embodiment.
In some embodiments, the optical lens 100 satisfies the following relationship: TTL/ImgH is less than 1.35; the TTL is the distance from the object side surface S1 of the first lens element L1 to the imaging surface 101 of the optical lens assembly 100 on the optical axis O, i.e., the total optical length of the optical lens assembly 100, and ImgH is the radius of the maximum effective imaging circle on the imaging surface 101 of the optical lens assembly 100, i.e., the half image height of the optical lens assembly 100.
By controlling the ratio of the total optical length and the half image height of the optical lens 100 within a reasonable range, the size of the optical lens 100 can be effectively controlled on the premise that the optical lens 100 has a larger image plane, so that the optical lens 100 has a more compact structure and ultrathin characteristics, meets the miniaturization design requirements, enables the optical lens 100 to be better mounted on light and thin electronic equipment, and simultaneously enables the optical lens 100 to be compatible with a large-size photosensitive chip, thereby being beneficial to improving the imaging quality of the electronic equipment. When the upper limit of the above conditional expression is exceeded, the total optical length of the optical lens 100 is excessively large, which results in an increase in the volume of the optical lens 100, which is disadvantageous in the miniaturization design of the optical lens 100.
In some embodiments, the optical lens 100 satisfies the following relationship: 0.78< f1/f2<1.02; wherein f1 is the focal length of the first lens L1, and f2 is the focal length of the second lens L2.
The first lens element L1 with positive refractive power provides a portion of positive refractive power, and the second lens element L2 with positive refractive power can further converge light rays in cooperation with the first lens element L1. When the above conditional expression is satisfied, the refractive powers of the first lens element L1 and the second lens element L2 can be reasonably configured, which is beneficial to reducing the focal length of the optical lens 100, thereby being beneficial to further reducing the weight and weight of the optical lens 100. Meanwhile, the larger spherical aberration generated by the first lens element L1 and the second lens element L2 can be balanced, the configuration of the refractive power at the rear end of the optical lens 100 can be controlled, the correction of the peripheral aberration of the optical lens 100 can be enhanced, the aberration and the curvature of field of the whole optical lens 100 can be well corrected, and the overall resolution of the optical lens 100 can be improved. When the upper limit of the above condition is exceeded, the focal length of the first lens element L1 is too large, resulting in too weak refractive power, which is not conducive to the first lens element L1 collecting light from the object side, and is not conducive to the large-angle light entering the optical lens 100, resulting in reduced light flux, reduced field of view of the optical lens 100, and difficulty in meeting shooting requirements. When the focal length of the first lens element L1 is smaller than the lower limit of the above-mentioned relation, the refractive power is too high, which not only increases the sensitivity of the optical lens 100 and makes the processing difficult, but also increases the difficulty of correcting the aberration generated by the first lens element L1 and reduces the imaging quality.
In some embodiments, the optical lens 100 satisfies the following relationship: 2.5< R9/f <8.3; wherein R9 is a radius of curvature of the object side surface S9 of the fifth lens element L5 at the optical axis O, and f is a focal length of the optical lens 100.
When the above condition is satisfied, the convex surface design of the object side surface of the fifth lens element L5 at the paraxial region O is matched, so that the light rays can be further converged, and the focal length of the optical lens 100 can be controlled within a reasonable range, thereby being beneficial to compressing the total optical length of the optical lens 100, and enabling the optical lens 100 to satisfy the light, thin and miniaturized design requirements. When the upper limit of the above condition is exceeded, the radius of curvature of the object-side surface S9 of the fifth lens element L5 is larger, and the refractive power of the fifth lens element L5 is weakened, so that the focal length of the fifth lens element L5 is increased, which is disadvantageous for shortening the optical overall length of the optical lens 100; when the radius of curvature of the object-side surface S9 of the fifth lens element L5 is smaller than the lower limit of the above-described conditional expression, the refractive power of the fifth lens element L5 becomes stronger, which results in a smaller focal length of the fifth lens element L5, which tends to increase the burden of correcting aberrations of the sixth lens element L6, the seventh lens element L7, and the eighth lens element L8, thereby affecting the imaging quality.
In some embodiments, the optical lens 100 satisfies the following relationship: i f1/f8 <2.6; wherein f1 is the focal length of the first lens L1, and f8 is the focal length of the eighth lens L8.
When the above conditional expression is satisfied, the focal length of the first lens L1 can be controlled within a suitable range, so as to facilitate controlling the focal length of the entire optical lens 100, and further facilitate compressing the total optical length of the optical lens 100, so that the optical lens 100 satisfies the light, thin and miniaturized design requirement. When the upper limit of the above condition is exceeded, the absolute value of the focal length of the first lens element L1 is larger, which results in a weaker refractive power of the first lens element L1, which is not beneficial to compressing the total optical length of the optical lens 100, and thus is not beneficial to the light, thin and miniaturized design of the optical lens 100, or the absolute value of the focal length of the eighth lens element L8 is smaller, which is easy to increase the burden of the eighth lens element L8 for correcting curvature of field and astigmatism, thereby affecting the imaging quality of the optical lens 100.
In some embodiments, the optical lens 100 satisfies the following relationship: 1.8< R15/f8<2.1; wherein R15 is a radius of curvature of the object side surface S15 of the eighth lens element L8 at the optical axis O, and f8 is a focal length of the eighth lens element L8.
By satisfying the above conditional expression, the negative refractive power provided by the eighth lens element L8 can be controlled within a reasonable range, which is advantageous for correcting curvature of field, astigmatism and distortion of the optical lens 100, thereby ensuring the imaging quality of the optical lens 100. When the upper limit of the above condition is exceeded, the radius of curvature of the object side surface S15 of the eighth lens element L8 is larger, which makes it difficult to shorten the back focal length of the optical lens 100, resulting in a larger overall volume of the optical lens 100; when the curvature radius of the object-side surface S15 of the eighth lens element L8 is smaller than the lower limit of the above conditional expression, it is difficult to sufficiently correct curvature of field and aberration of the optical lens 100.
In some embodiments, the optical lens 100 satisfies the following relationship: 1< |SAG82/CT8| <2.2; wherein SAG82 is a sagittal height of the image side surface S16 of the eighth lens L8 at the maximum effective radius, that is, SAG82 is a distance from the maximum effective aperture of the image side surface S16 of the eighth lens L8 to a point of intersection of the image side surface S16 of the eighth lens L8 with the optical axis O in a direction parallel to the optical axis O, by default, a direction of the object side surface S1 of the first lens L1 to the image side surface S16 of the eighth lens L8 is a positive direction of the optical axis O, when the SAG82 value is negative, the point of intersection of the image side surface S16 of the eighth lens L8 with the optical axis O is left, and when the SAG82 value is positive, the point of intersection of the image side surface S16 of the eighth lens L8 with the optical axis O is right. CT8 is the thickness of the eighth lens L8 on the optical axis O.
The ratio of the sagittal height of the image side surface S16 of the eighth lens L8 at the maximum effective radius to the center thickness of the eighth lens L8 is reasonably constrained, so that the relative illuminance of the edge of the imaging surface 101 of the optical lens 100 is ensured, the risk of occurrence of a dark angle is reduced, the aberration of the optical lens 100 can be effectively corrected, the imaging quality of the optical lens 100 is improved, the sagittal height of the image side surface S16 of the eighth lens L8 at the maximum effective radius and the center thickness of the eighth lens L8 can be constrained within a reasonable range, the surface shape of the eighth lens L8 is prevented from being excessively distorted, the surface shape of the eighth lens L8 is controlled within a range easy to process and form, and the processing and forming of the eighth lens L8 are facilitated. When the upper limit of the above condition is exceeded, the image side surface S16 of the eighth lens L8 is excessively high at the maximum effective radius, which results in excessively distorted surface shape of the eighth lens L8, so that the lens assembly difficulty of the optical lens 100 is increased, and the chief ray angle of the optical lens 100 is difficult to match with the chief ray angle of the photosensitive chip, which is not beneficial to the improvement of the imaging quality of the optical lens 100; when the refractive index is lower than the lower limit of the above condition, the sagittal height of the image side surface S16 of the eighth lens L8 at the maximum effective aperture is smaller, so that the higher-order aberration of the off-axis field is difficult to be effectively balanced, and the deflection angle of the marginal ray when entering the eighth lens L8 is too large, so that the tolerance sensitivity of the lens is increased, which is unfavorable for the assembly of the lens.
In some embodiments, the optical lens 100 satisfies the following relationship: 1.6< |r4/f2| <9.3; wherein R4 is a radius of curvature of the image side surface of the second lens element L2 at the optical axis O, and f2 is a focal length of the second lens element L2.
When the above condition is satisfied, the second lens element L2 has positive refractive power, and the radius of curvature of the image-side surface S4 of the second lens element L2 at the optical axis O can be reasonably controlled to match the first lens element L1 to share a portion of the positive refractive power, so as to improve the light converging capability of the optical lens 100, shorten the total optical length of the optical lens 100, and achieve light, thin and compact optical lens 100. When the upper limit of the above condition is exceeded, the absolute value of the curvature radius of the image side surface S4 of the second lens L2 at the optical axis O is large, so that the surface shape of the second lens L2 is too gentle, and it is difficult to sufficiently correct astigmatism and distortion; when the lower limit of the above condition is exceeded, the absolute value of the curvature radius of the image side surface S4 of the second lens L2 at the optical axis O is too small, resulting in excessive surface curvature of the second lens L2, which increases the burden of correcting coma aberration of the third lens L3.
In some embodiments, the optical lens 100 satisfies the following relationship: -6< (f6+f7)/f8 < -5; where f6 is the focal length of the sixth lens L6, f7 is the focal length of the seventh lens L7, and f8 is the focal length of the eighth lens L8.
When the above condition is satisfied, the total length of the optical lens 100 can be further shortened by matching the positive refractive power provided by the sixth lens element L6 and the seventh lens element L7, so that the optical lens 100 can satisfy the light, thin and miniaturized design requirements. When the upper limit of the above conditional expression is exceeded, the focal length of the seventh lens L7 of the sixth lens L6 is too small, so that the positive refractive powers of the sixth lens L6 and the seventh lens L7 are too strong, and the burden of correcting aberration of the eighth lens L8 is excessively increased, which is unfavorable for improving the imaging quality; when the focal length of the seventh lens element L7 of the sixth lens element L6 is smaller than the lower limit of the above-mentioned conditional expression, the positive refractive power of the sixth lens element L6 and the seventh lens element L7 is too large, which is disadvantageous for the overall optical length of the optical lens element 100 to be compressed, and thus is disadvantageous for the light and thin and compact design of the lens element.
In some embodiments, the optical lens 100 satisfies the following relationship: 5.3mm < f tan (HFOV) <5.5mm; where f is the focal length of the optical lens 100 and HFOV is half the maximum field angle of the optical lens 100.
When the above-mentioned conditional expression is satisfied, it is not only advantageous to reduce the deflection angle of the incident light in the optical lens 100, so that the surface shape of each lens in the optical lens 100 is not excessively bent or gentle, but also advantageous to the manufacturing process of each lens. In addition, when the optical lens 100 satisfies the above conditional expression, the angle of view and the image height of the optical lens 100 can be reasonably configured, and on the one hand, the axial dimension of the optical lens 100 can be further compressed; on the other hand, the optical lens 100 can have the characteristic of a large image plane, so that when the optical lens 100 is applied to the image capturing module, the optical lens 100 can be matched with a large-size photosensitive chip of the image capturing module, and further, the imaging quality of the optical lens 100 is improved. When the upper limit of the above condition is exceeded, the focal length of the optical lens 100 is too long, which makes it difficult to compress the total optical length of the optical lens 100, resulting in an increase in the volume of the optical lens 100, which is disadvantageous for the optical lens 100 to meet the miniaturization design requirement. When the angle of view of the optical lens 100 is smaller than the lower limit of the above conditional expression, the field of view of the optical lens 100 is reduced, resulting in insufficient imaging information of the optical lens 100 and affecting the shooting quality of the optical lens 100.
In some embodiments, the optical lens 100 satisfies the following relationship: 1.4< R12/f <1.7; wherein R12 is a radius of curvature of the image side surface S12 of the sixth lens element L6 at the optical axis O, and f is a focal length of the optical lens 100.
By satisfying the above-described relational expression, the curvature radius of the image side surface S12 of the sixth lens L6 at the optical axis O can be controlled within a reasonable range, and astigmatism, curvature of field, and distortion can be corrected well. When the curvature radius of the image side surface S12 of the sixth lens element L6 at the optical axis O is smaller than the lower limit of the above-mentioned conditional expression, the curvature of the surface of the sixth lens element L6 is too large, which increases the sensitivity of the sixth lens element L6 and is not beneficial to the engineering manufacture of the sixth lens element L6; when the upper limit of the above condition is exceeded, the curvature radius of the image side surface S12 of the sixth lens L6 at the optical axis O is too large, resulting in excessively gentle surface shape of the sixth lens L6, which makes it difficult to sufficiently correct astigmatism, field curvature, and distortion.
In some embodiments, the optical lens 100 satisfies the following relationship: the optical lens 100 satisfies the following relationship: 1< f6/f7<1.4; where f6 is the focal length of the sixth lens L6, and f7 is the focal length of the seventh lens L7.
Since both the sixth lens element L6 and the seventh lens element L7 can provide positive refractive power, the focal length ratio of the sixth lens element L6 to the seventh lens element L7 can be controlled within the above range, so that the refractive power can be reasonably shared by the sixth lens element L6 and the seventh lens element L7, and the spherical aberration contribution of the sixth lens element L6 and the seventh lens element L7 can be kept within a reasonable range, which is beneficial to improving the imaging quality of the optical lens 100 in the field of view region on the optical axis O, so that the effective pixel region on the imaging surface 101 of the optical lens 100 has good imaging quality; and at the same time, it is beneficial to further shorten the total optical length of the optical lens 100 to meet the miniaturization design of the optical lens 100.
The optical lens 100 of the present embodiment will be described in detail below with reference to specific parameters.
First embodiment
As shown in fig. 1, the optical lens 100 according to the first embodiment of the present application includes a stop 102, a first lens L1, a second lens L2, a third lens L3, a fourth lens L4, a fifth lens L5, a sixth lens L6, a seventh lens L7, an eighth lens L8, and an optical filter L9, which are sequentially disposed from an object side to an image side along an optical axis O.

The elements from the object side to the image side are sequentially arranged in the order of the elements from top to bottom in table 1 along the optical axis O of the optical lens 100. In the same lens element, the surface with smaller surface number is the object side surface of the lens element, and the surface with larger surface number is the image side surface of the lens element, and the surface numbers 1 and 2 correspond to the object side surface S1 and the image side surface S2 of the first lens element L1, respectively. The radius Y in table 1 is the radius of curvature of the object or image side of the corresponding surface number at the paraxial region O. The first value in the "thickness" parameter array of the lens is the thickness of the lens on the optical axis O, and the second value is the distance from the image side surface of the lens to the latter surface on the optical axis O. The value of the diaphragm 102 in the "thickness" parameter row is the distance between the diaphragm 102 and the vertex of the subsequent surface (the vertex refers to the intersection point of the surface and the optical axis O) on the optical axis O, and the direction from the object side surface of the first lens L1 to the image side surface of the last lens is the positive direction of the optical axis O by default, when the value is negative, it indicates that the diaphragm 102 is disposed on the right side of the vertex of the subsequent surface, and when the thickness of the diaphragm 102 is positive, the diaphragm 102 is on the left side of the vertex of the subsequent surface. It is understood that the units of Y radius, thickness, and focal length in Table 1 are all mm. And the reference wavelength of the focal length, refractive index, abbe number of each lens in table 1 was 587.60nm.
