Photographic device two-view camera [Prior Art] or CMOS # photographic element miniaturization and high image 10 15 years of rapid development. At the same time, it is also necessary to reduce the size and weight of the camera. In the case of a car camera or a surveillance camera, it is required to have a (4) sex and a summer lens from an outdoor dragon belt in a cold area. The small and wide-angle ' and the high-performance horse that can be used in the temperature range can be used in the conventional photographic lens, and can be applied to the camera for vehicles or to monitor the camera. The lens includes, for example, the photographic lenses described in the following patents Acer & No. 4, No. 4 to 5; [Patent Document No. 1] JP-A-2006-259704; [Patent No. 2] JP-A-2002-244031; [Patent Month lj Case 3] Special Publication No. 2005-227426; [Patent Case 4] Japanese Laid-Open Patent Publication No. 2001-337268; M355384 ... [Patent 5 of the Japanese Patent Application Laid-Open No. Hei No. Hei. 。 。 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In addition to the miniaturization of the photographic lens described in the fourth patent, the lens on the object side is a plastic lens. Therefore, for example, when used in a vehicle-mounted camera, the most object of the lens on the most object side. The side requires a glass cover ^ etc. 10 protective parts, resulting in an increase in size of the device. • The photographic lenses described in Patent Document 5 are all spherical lenses, so there is still improvement in aberration correction compared with systems using aspheric lenses. [New content] This creation is based on the above situation. The object of the invention is to provide a photographic lens that is small and wide-angle and maintains good imaging performance, and an imaging device including the photographic lens. ~ The photographic lens created by the quotation is formed from the front side of the object side by a front group having a negative refractive power and a rear group having a positive refractive power, and has a tangent line and an optical axis according to a prescribed point in the lens surface area. The acute angle becomes 3 inches. The following methods include the aspheric surfaces of the above specified points. In addition, the "effective area" of the 'lens surface' indicates an area in which the total ray passing through the lens surface and used in the imaging of the subject image and the intersection with the lens surface is M355384. If the optical axis is symmetrical, then The so-called "effective within the path" and "effective area" are consistent. Because in the system of optical axis symmetry, the "effective path" refers to the outermost part of the total light that passes through the lens surface and is used in the imaging of the subject image (the farthest from the optical axis) The diameter of the circle depicted by the intersection of the light and the 忒 lens surface. The effective area is determined, for example, by the specifications of the aperture stop or the photographic lens.

Here, the "peripheral portion of the effective field" is the outermost J of the total ray used by the lens on the lens surface and used for imaging the subject image (the position farthest from the optical axis) The part where the light is intersected with the lens surface. In an optical axis-symmetric system, the point of the peripheral portion of the effective region coincides with the point at the effective diameter end. Preferably, the photographic lens of the present invention is a lens in which the object-side lens of the front group is negative, and the rear group includes a light barrier and at least two lenses. The photographic lens of the present invention is configured such that the front group is formed by the negative of the first mirror and the negative second lens from the object side, and the first group of the first lens, the light barrier, and the positive fourth from the object side. A lens is also available. The photographic lens of the present invention may be formed by a first lens, a negative second lens, a positive second lens, a light barrier, and a positive first lens. The front group has a negative lens from the object side, and the photographic lens created by the fourth lens from the object side by the four lenses and the positive or negative fifth through the non-state 2, the front group has the aspheric surface including the above specified points. Can be 'or after the group has a fixed point (four) spherical surface can also be included. In the present creation, in the case of an aspherical lens, the "positive lens" table 20 M355384 shows a lens having a positive refracting power in the paraxial region of the lens, "the negative lens table does not have a negative refracting power in the paraxial region of the lens. The lens of the present invention is characterized in that it has the imaging lens of the above-described creation. 5 Further, the numerical value of the Abbe number described in the present specification is a numerical value at the d line (587.56 nm). In the photographic lens, the front group has a negative refracting power and the rear group has a positive refracting power, so it is advantageous for wide-angle. Moreover, the photographic lens of the present invention has an acute angle formed by a tangent line and an optical axis according to a prescribed point of the effective field. Since the method of the following 30 points includes the aspherical surface of the predetermined point described above, various aberrations can be effectively corrected, and the entire system can be miniaturized and miniaturized. The imaging device of the present invention includes the above-described imaging lens of the present invention, and thus can be configured. It is small, and can be photographed in a wide-angle range, and a good image can be obtained. 15 [Embodiment] Hereinafter, the present invention will be described with reference to the drawings. The embodiment of the present invention is shown in Fig. 1. A lens cross-sectional view of a cross section including an optical axis Z of an imaging lens i 2 according to an embodiment of the present invention is shown in Fig. 1. The on-axis beam 2 of the object point, the off-axis light of the maximum viewing angle "The on-axis beam is the beam from the object point of the light extraction, and the axis beam is the beam from the object point outside the optical axis. Further, the configuration J shown in Fig. 2 is constituted by the lens of the embodiment 后 described later in Fig. 2 . Figs. 3 to 7 show lens cross-sectional views of a cross section including the optical axis z M355384 of another configuration example of the photographic lens of the present invention, which corresponds to the lens configuration of the second to fourth embodiments described later. First, the basic configuration of the imaging lens according to the present embodiment will be described by taking the imaging lens 1 having the configuration shown in Fig. 1 as an example. The photographic lens 1 of the example shown in Fig. 5 is formed of a lens L11, a lens L12, a lens L21, an aperture stop St, and a lens L22 in this order from the object side. The aperture stop st in Fig. 1 does not indicate its shape or size, but its position on the optical axis Z. In the figure, in consideration of the case where the photographing lens is used for the photographing apparatus, the photographing element 5 disposed on the image plane including the image forming position Pim of the photographing lens i is also illustrated. The photographic element 5 converts the optical image formed by the photographic lens ί into an electrical signal. For example, the ccd image sensing 15 is preferably used to configure the glass cover in accordance with the configuration of the camera side of the loading lens. The low-pass data device, the infrared ray cut-off, the sleek moon, and the like do not have an example in which these conceivable parallel flat optical port P pieces PP are disposed between the lens system and the photographic element 5. For example, when used in an on-vehicle camera, when used as a night vision assisted night = eyepiece, a filter that cuts off ultraviolet light to blue light may be inserted between the lens system and the photographing element. Wave center: Low-pass is placed between the lens stop system and the photographic element 5. Various filters 'A variety of slides can be placed between the lenses. Or, a coating having the same function as that of the various calenders is applied to the lens surface of the lens of the lens 1 : 20 M355384 The photographic lens of the present embodiment is roughly described by the object side. A pre-group GF having a negative refracting power and a rear group GR having a positive refracting power. Thus, by adopting a retrofocus (also referred to as an anti-distance) configuration in which the front group has a negative refracting power and the rear group has a positive refracting power, it is advantageous for wide-angle. In the example shown in Fig. 1, the front group GF is formed by a lens Lu and a lens L12, and the rear group GR is formed by a lens L21 and an aperture stop with a lens. The fF is a characteristic structure, and the following is a method in which the tangential line of the effective area of the lens surface and the optical axis are formed as an acute angle, and the following method includes the aspheric surface of the predetermined point (hereinafter, referred to as deep Surface aspherical).

In the example, the imaging side S4 of the first oscillating blade is the aspherical surface of the deep curved surface, and the tangential line 4 of the lens surface at the point X4 of the surface and the optical axis z# & 2 are hereinafter corrected by including such == At the same time of aberrations, it is easy to wide: "Γ面' can effectively minimize the entire system, such as J, which can be set as an effective diameter end. It is difficult to process the optical axis and the optical axis. The acute angle becomes 18. Hereinafter, the acute angle is preferably two to two limits, and various aberrations can be corrected well. The cost increase is controlled at a minimum of 8 M355384. The surface aspheric surface can be easily corrected for distortion according to the position in the front group gf. The mode configuration may also be that the deep curved aspheric surface is in the front group GF, and the front group rp m 由 is determined by the negative first-heart self-twisting # and the GF is preferably the imaging side of the second lens from the object side. According to this composition == Yi Cai father orthodontics. v The valley surface of the ice surface is composed of μ·η±-Γή in the rear group GR, and it can also be used to correct the curvature of field and the chromatic aberration of magnification. When the aspherical surface of the deep surface is in the rear group GR, the aspheric surface of the deep surface is smaller than the side of the object of the object side lens of the rear group GR. According to this configuration, it is possible to further easily correct the field curvature and the chromatic aberration of magnification. Further, as the configuration of the front feGF and the rear group GR of the photographing lens, it is preferable that the most object-side lens of the front group GF is a negative lens, and the rear group gr includes an aperture stop St and at least two lenses. In particular, the aperture stop & preferably 15 is disposed between the lenses included in the rear group GR. By making the most object-side lens of the front group GF a negative lens, it is possible to capture light incident at a large angle, and thus it is easy to widen the system. The post-group GR includes at least two lenses, and the aberration is easily corrected. The through-group GR includes the aperture stop St, and the aperture stop St is also disposed on the imaging side in the entire system, and is easily wide-angled. Specifically, for example, the example shown in FIG. 1 may be configured such that the front group GF is formed of a negative first lens and a negative second lens in order from the object side, and the rear group GR is positive from the object side in order. The third lens, the aperture stop, and the positive fourth lens are formed. M355384 is such that when the front group GF is composed of two negative lenses, the distortion can be easily corrected while further widening the valley, and the rear group gR is composed of two positive lenses and an aperture stop St disposed therebetween. It can well correct spherical aberration (also called spherical aberration), image curvature (also called field curvature), and coma aberration 5 (also called coma). Further, the configuration of the front group GF and the rear group GR is not limited to the example shown in Fig. 1, and various methods may be employed. For example, the front group GF may be formed of a negative first lens and a negative second lens in order from the object side, and the rear group GR may be a positive third lens, an aperture stop, and a positive 10 from the object side. The fourth lens is formed with a positive or negative fifth lens. The effect when the front group GF is constituted by two negative lenses is as described above. The spherical aberration, the field curvature, and the coma aberration can be further satisfactorily corrected by the third lens, the aperture stop, the fourth lens, and the fifth lens as described above, and -GR. When the lens on the most object side of the rear group GR is a positive lens, the Abbe number of the material constituting the side lens is preferably 4 Å or less. According to this configuration, the chromatic aberration of magnification can be favorably corrected. In the lens configuration including the fourth lens, the Abbe number of the lens material constituting the fourth lens is preferably 45 or more. According to this configuration, the chromatic aberration of magnification can be corrected satisfactorily. In the lens configuration including the fifth lens, the Abbe number of the lens material constituting the fifth lens is preferably 45 or less. According to this configuration, the chromatic aberration on the shaft can be favorably corrected. 10 M355384 More specifically, the photographic lens may adopt the first, second, and third modes described below. [First Mode] In the first aspect, the front group GF is formed by a first lens having a concave surface facing a negative 5 on the imaging side, and the rear group GR is sequentially a positive second lens, an aperture stop, from the object side. A positive third lens is formed. The first lens is preferably a negative meniscus lens. Further, if the first lens is a negative meniscus lens having a concave surface toward the object side, for example, the incident angle may be captured more than 100. The light can widen the entire system. 10 The first lens may be a plano-convex lens that has a concave surface toward the imaging side. Further, the first lens may be a double concave lens having an absolute value of the radius of curvature of the side of the object larger than the absolute value of the radius of curvature of the image side. The biconcave lens 15 having a convex lens whose concave surface faces the image side, or a concave lens 15 whose absolute value of the curvature radius of the object side surface is larger than the absolute value of the curvature radius of the imaging side surface is wider. In the first mode, if the first lens is a negative meniscus lens with a concave surface facing the object side, and at least one side surface is aspherical, it can also be captured: Example: In: Angle exceeds 10 ° ° light 'can be used to widen the entire system, correct distortion, face curvature and so on. In the first mode, the aspherical surface of the deep curved surface is preferably the second transparent side surface. At this time, the curvature of field and the chromatic aberration of magnification are easily corrected. In the first mode, the material constituting the second lens is below. In this case, the chromatic aberration of magnification can be satisfactorily corrected.

In the second aspect, it is preferable that the material for forming the first lens is glass, and the material of the first lens, the second lens, and the fourth lens is plastic. By using the first lens as a glass lens, it is possible to produce a high weather resistance at a low cost. When the first lens is a spherical lens, a lens can be produced at a low cost. The second lens, the third lens, and the fourth lens are provided as plastic lenses, and the entire system is small and lightweight, and the lens system is low in cost. [Third mode] 13 M355384 *- In the third mode, the front group gf is formed of, in order from the object side, a first lens having a concave meniscus lens having a concave surface toward the imaging side, and a negative second lens.

By using the first lens as a glass transparent hie. Brother can produce a lens with high weather resistance at a low price. By using the second lens, the second lens, the fourth lens, and the fifth lens as plastic aspherical lenses, While the various aberrations are well corrected, the entire system is small and lightweight, and the lens system can be further reduced in price. The further step of the photographic lens can be as described below. [Other preferred modes] 15 M355384 " Set the focal length of the entire system to f, and set the distance from the object side of the object-side lens of the entire system to the imaging surface to L (when the back-intercept (backf0cus) amount is long in air conversion), It is preferable to satisfy the following conditional expression (1): 5 3. 〇 <L/f < 18.0 (1) When the upper limit of the conditional expression (1) is exceeded, the overall length becomes longer and the system becomes larger. When the lower limit of the conditional expression (丨) is too long, the focal length of the entire system is too long, and the wide angle is insufficient, or in order to achieve wide angle, it is necessary to ensure that the viewing angle is excessively distorted and the surrounding image is excessively distorted by distortion. The thickness of .10 of each lens is reduced to deteriorate the workability. In order to reduce the size, the above L is preferably 15 mm or less. In the photographic lens of the present embodiment, the focal length of the entire system is set to f' from the entire system. By imaging side lens When the distance from the side to the image plane (the so-called back intercept) is Bf, it is preferable to satisfy the following conditional expression 15 (2): 〇.5 < Bf / f < 3.0 (2). Lu Ru exceeds the conditional expression If the upper limit of (2) is longer, the system becomes larger, and if the lower limit of the conditional expression (2) is exceeded, it is difficult to insert a glass cover or various filters between the lens system and the photographic element. In the photographic lens of the present embodiment, the composite focal length of the front group GF is set to fA, and the composite focal length of the rear group GR is preferably set to satisfy the following conditional expression (3): 0.01 < | fA/fB | < 3.00 ...(3). 16 M355384 If the upper limit of the upper [day] of the conditional expression (3) is exceeded, the image plane curvature becomes large, and it is difficult to obtain a good image. If the lower limit of the strip # < .._ 弋 弋 (3) is exceeded, it is difficult to miniaturize the system. When the focal length of the entire system is set to ft, it is preferable that in the photographic lens of the present embodiment, f, the object-side lens of the front group GF satisfies the following conditional expression (4): 0· 5<I fi/f 丨< 15.0 (4). In order to widen the lens system, it is preferable to set the most object side lens of the front group gf as a negative lens. When the object-side lens of the front group GF is a negative lens, if the upper limit of the conditional expression (4) is exceeded, the refractive power of the negative lens is weak, and it is difficult to achieve wide angle. When the lower limit of the conditional expression (4) is exceeded, the wide angle can be easily achieved, but it is difficult to correct the field curvature. When the photographic lens has the fourth lens and the fifth lens as described above, the focal length of the entire system is f, and when the δ focal length of the fourth lens and the fifth lens is set to the center 5, it is preferably The following conditional formula ($) is satisfied: 0-5 <f45/f< 3.0 ... (5). When the upper limit of the conditional expression (5) is exceeded, the combined refracting power of the fourth lens and the fifth lens becomes too weak, and it is difficult to satisfactorily correct chromatic aberration. If the lower limit of the formula (5) is exceeded, the combined diopter of the fourth lens and the fifth lens becomes too strong, so that the back intercept becomes short. If the photographic lens is used for a photographic device having a photographic element, It is difficult to insert various filter moons or glass covers between the lens system and the photographic element.

The imaging side of the most imaging side lens of the uranium group GF to the optical axis of the object side of the object side lens of the rear group GR 17 M355384 When the upper focal length is set to MB, it is preferable to satisfy the following conditional expression (6): 0.5 < DAB/f < 5.0 (6). By satisfying the conditional expression (6), the aberration _ can be corrected satisfactorily, and the size can be reduced. If the upper limit of the conditional expression (6) is exceeded, the distance between the front group GF and the rear group GR becomes large, so that the light of the front group GF becomes high, and the lens system is enlarged. If the lower limit of the conditional expression (6) is exceeded, the front group and the rear group GR are too close, so the light height in the front group becomes too small, and f becomes difficult to pass through the front group GF, and the filament light and the off-axis light are separated. It is difficult to correct distortion or image curvature well. When the photographic lens is used for, for example, a vehicle-mounted camera, it is required to be used in a wide-area temperature range 2 in a car in the summer from a cold area to a tropical place. When the temperature range of the wide area is used, it is preferable to use a material having a small coefficient of linear expansion as the lens material. 15 When the photographic lens is used in a strict environment such as a vehicle-mounted camera or a surveillance camera, it is preferable to use a lens disposed on the side of the sin-object in the entire system. Resistant to the cracking of the surface of the wind and rain, the temperature of the direct sunlight is better. It is better to use chemicals that are resistant to chemicals such as grease and detergents, that is, in weather conditions, high acid resistance, high chemical resistance, etc. Material. The material of the lens placed on the side of the core object is preferably a solid and difficult to be used. I: From the above, 'as a lens material disposed on the most object side, it is preferable to use glass, or use transparent ceramics. . Ceramics are more resistant to general-purpose glass and have a heat-resistant 20 M355384 " or a cover member such as a glass cover that is disposed on the object side of the most object-side lens and is provided with a protective lens system. also may. The cover member may be a parallel flat plate or a curved surface having no refracting power. A protective film for a protective film system such as a hard film disposed on the side of the lens object disposed on the most object side may be a film formed on the side surface of the lens object disposed on the most object side. When the cover member is disposed closer to the object side than the most object-side lens, the lens disposed on the most object side may be a plastic aspheric lens. Lu is made up of a plastic aspherical lens through the lens disposed on the most object side, and the lens system can be made small, lightweight, and inexpensive while correcting various aberrations. It is preferable to use a plastic material as the material of each of the transmissive mirrors on the imaging side of the lens disposed on the most object side. By using these lens materials as plastics, an aspherical shape can be accurately produced, and good optical properties can be obtained. And by using plastic, the lens system can be made low-cost and lightweight. As the material of each of the mirrors on the imaging side of the lens disposed on the most object side, a so-called nanocomposite film material in which particles having a smaller wavelength than the light are mixed in the plastic may be used. The nanocomposite film material can change the refractive index and Abbe number of the material through the mixed particle type or ®. By using the 20-m2 composite film material, for example, a material having a surface refractive index or a material having a small Abbe number which cannot be obtained from the conventional plastic material can be produced. Thus, a lens having good optical properties can be produced. 19 M355384 It is preferable to use a material having a refractive index of 1 > 6 or more as a mirror material on the imaging side of the lens disposed on the most object side. The lens system can be further miniaturized by using a material having a refractive index of 1.6 or more. Further, the lens surface using a material having a refractive index of i.6 or more can be further reduced in size by making it a deep curved aspheric surface.

As the light shielding means, for example, an opaque paint may be applied to the outer portion of the effective diameter of the image forming side of the lens, or a plate having no lens may be provided. Alternatively, an opaque plate may be provided as a light shielding means on the optical path of the beam of the stray light. As an example, in Fig. i, an example in which the light shielding means U'12 is provided on the imaging side faces of the first lens L1 and the second lens L2 is shown. Further, the light shielding means is not limited to the example shown in Fig. i, and may be disposed between other lenses as needed.
