An optical imaging lens according to an exemplary embodiment of the present application has, for example, two lens groups, i.e., a first lens group and a second lens group. The two lens groups are arranged in order from an object side to an image side along an optical axis.

Wherein the first lens may have a positive optical power; the second lens may have a negative optical power; and the optical element has no optical power; through reasonable configuration, under the condition that the focal power of the whole system and the focal power of each lens are basically unchanged, the peripheral field aberration is corrected by utilizing the double-sided aspheric surface, so that the low-order aberration of the control system can be effectively balanced, the optical imaging lens obtains better imaging quality, the aperture can be favorably increased, and the miniaturization of the lens is ensured.
In an exemplary embodiment, the second lens group may include one optical element having no optical power and three lenses having optical power, wherein one lens closest to an imaging surface of the optical imaging lens among the three lenses having optical power may have negative optical power.
In another exemplary embodiment, the second lens group may include two optical elements having no optical power and two lenses having optical power, wherein one of the two lenses having optical power closest to an imaging surface of the optical imaging lens may have negative optical power.

In an exemplary embodiment, a radius of curvature R1 of the object-side surface of the first lens and a radius of curvature R4 of the image-side surface of the second lens may satisfy: 0. Ltoreq. R1/R4. Ltoreq.1, more specifically, 0.14. Ltoreq. R1/R4. Ltoreq.0.57 can be further satisfied.

By the configuration, the light transmission quantity can be increased, the system has the advantage of large aperture, and the imaging effect in a dark environment is enhanced.

With such a configuration, it is possible to have good imaging quality while ensuring miniaturization of the lens.
In an exemplary embodiment, the radius of curvature RL1 of the lens object side surface closest to the imaging surface and the radius of curvature RL2 of the lens image side surface closest to the imaging surface may satisfy: and more specifically, the condition that the absolute RL1+ RL 2/RL 1-RL2 is less than or equal to 3 can be further met. With such a configuration, it is possible to help match the incident angle of the principal ray of the chip, thereby improving the relative brightness while correcting astigmatism.
In an exemplary embodiment, an abbe number V1 of the first lens and an abbe number Vne of the optical element having no optical power may satisfy: the | Vne-V1| is less than or equal to 40, and more specifically, the | Vne-V1| is less than or equal to 33.74. Aberrations can be corrected by abbe number interactions between different materials.
In an exemplary embodiment, a sum Σ AT of air intervals on the optical axis between any adjacent two lenses having optical powers of the first lens to the lens closest to the imaging surface and an effective focal length f of the optical imaging lens may satisfy: sigma AT/f is 0. Ltoreq. 1.1, and more specifically, 0.20. Ltoreq. Sigma AT/f. Ltoreq.1.05 can be further satisfied. By such a configuration, miniaturization of the lens can be ensured, and by changing the distance on the axis, the light deflection tends to be relaxed, the generation of corresponding aberration is reduced, and the sensitivity is reduced.
In an exemplary embodiment, the optical imaging lens may further include a stop STO for limiting a light beam, and the amount of light entering is adjusted to improve the imaging quality. The optical imaging lens according to the above-described embodiment of the present application may employ a plurality of lenses, for example, six lenses as described above. By reasonably distributing the focal power, the surface type, the central thickness of each lens, the on-axis distance between each lens and the like, the aperture of the optical imaging lens can be effectively enlarged, the system sensitivity is reduced, the miniaturization of the lens is ensured, and the imaging quality is improved, so that the optical imaging lens is more favorable for production and processing and is suitable for portable electronic products. In the embodiment of the present application, at least one of the mirror surfaces of each lens is an aspherical mirror surface. The aspheric lens is characterized in that: the curvature varies continuously from the center to the periphery of the lens. Unlike a spherical lens having a constant curvature from the center to the periphery of the lens, an aspherical lens has a better curvature radius characteristic, has the advantages of improving distortion aberration and astigmatic aberration, and can make the field of view larger and more realistic. After the aspheric lens is adopted, the aberration generated during imaging can be eliminated as much as possible, thereby improving the imaging quality. In addition, the use of the aspherical lens can also effectively reduce the number of lenses in the optical system.
However, it will be appreciated by those skilled in the art that the number of lenses constituting the lens barrel may be varied to achieve the various results and advantages described in the present specification without departing from the claimed subject matter. For example, although six optical elements are exemplified in the embodiment, the optical imaging lens is not limited to including six optical elements. The optical imaging lens may also include other numbers of lenses, if desired.
Specific examples of an optical imaging lens applicable to the above-described embodiments are further described below with reference to the drawings.
Example 1
An optical imaging lens according to embodiment 1 of the present application is described below with reference to fig. 1 to 2D.
Fig. 1 shows a schematic structural diagram of an optical imaging lens according to embodiment 1 of the present application.

Wherein the first lens group includes a first lens E1 and a second lens E2; the second lens group includes a third lens E3, an optical element DOE, a fourth lens E4, and a fifth lens E5 closest to the image plane. The first lens E1 has an object side surface S1 and an image side surface S2; the second lens E2 has an object side surface S3 and an image side surface S4; the third lens E3 has an object-side surface S5 and an image-side surface S6; the optical element DOE has an object-side surface S7 and an image-side surface S8; the fourth lens E4 has an object side surface S9 and an image side surface S10; and the fifth lens E5 closest to the image plane has an object-side surface S11 and an image-side surface S12.
In this embodiment, the first lens E1 may have positive optical power; the second lens E2 may have a negative power; the third lens E3 has negative power; the object side surface and the image side surface of the optical element DOE are both aspheric surfaces and have no focal power; the fourth lens E4 has positive optical power; and the fifth lens E5 closest to the image plane may have a negative power.

The light from the object passes through the respective surfaces S1 to S14 in order and is finally imaged on the imaging plane S15.

As can be seen from table 1, the radius of curvature R3 of the object-side surface of the second lens element and the radius of curvature R4 of the image-side surface of the second lens element satisfy | R3-R4|/| R3+ R4| =0.37; the curvature radius R1 of the object side surface of the first lens and the curvature radius R4 of the image side surface of the second lens meet R1/R4=0.43; sigma CT/sigma AT =1.66 is satisfied between a sum sigma CT of central thicknesses of respective lenses having powers of the first lens to the lens closest to the imaging surface and a sum sigma AT of an air space on the optical axis between any adjacent two lenses having powers of the first lens to the lens closest to the imaging surface; and the radius of curvature RL1 of the lens object side surface closest to the imaging surface and the radius of curvature RL2 of the lens image side surface closest to the imaging surface satisfy the condition of RL1+ RL2|/| RL1-RL2| =0.35.
In the embodiment, six optical elements are taken as an example, and the focal length and the surface type of each lens are reasonably distributed, so that the aperture of the lens is effectively enlarged, the total length of the lens is shortened, and the large aperture and the miniaturization of the lens are ensured; meanwhile, various aberrations are corrected, and the resolution and the imaging quality of the lens are improved. Each aspherical surface type x is defined by the following formula:

wherein x is the distance rise from the vertex of the aspheric surface when the aspheric surface is at the position with the height of h along the optical axis direction; c is the paraxial curvature of the aspheric surface, c =1/R (i.e., paraxial curvature c is the inverse of radius of curvature R in table 1 above); k is the conic coefficient (given in table 1 above); ai is the correction coefficient of the i-th order of the aspherical surface.
