By arranging the negative first lens and the second lens on the most object side, light incident from a large angle of view can be captured, and the optical system can be wide-angled. By forming at least one side surface of the second lens as an aspherical surface, the lens system can be miniaturized while satisfactorily correcting aberrations. Since the light passing through the second lens axis and the off-axis light are separated, when the lens surface is formed into an aspherical surface, it is advantageous to correct the aberration and it is easier to correct the distortion. It should be noted that the first lens also separates the on-axis ray and the off-axis ray/knife, but as the material of the first lens disposed on the most object side of the lens system, it is preferable to use the glass as described below. material. Further, in the lens system, since the first lens is the lens having the largest diameter, it is preferable to form the second lens to which the plastic material is applied to be aspherical in terms of lens manufacturing and aberration correction. The third lens, the fourth lens, and the sixth lens are each formed into a lens having at least one side aspherical surface and having a positive refracting power, and an aperture diaphragm is disposed between the third lens 2 〇 and the fourth lens The lens system can be miniaturized while satisfactorily correcting the spherical aberration 'image surface aberration and coma aberration. By forming the third lens and the fifth lens from a material having an Abbe number of 45 or less on the d line, the axial chromatic aberration and the chromatic aberration of magnification can be satisfactorily corrected. M363171 By using the first lens as a glass lens, it is possible to manufacture a photographic lens that is highly resistant to weathering. By fabricating the lenses of the second lens to the sixth lens from a plastic material, the aspherical shape can be correctly reproduced, and the lightweight lens system can be manufactured at a low cost. According to the second photographic lens of the present invention and the photographic apparatus using the photographic lens, since the first lens is disposed in order from the object side, it has a negative refracting power and is a meniscus lens having a concave surface toward the imaging side; the second lens, And/or having a negative refracting power' and at least one lens surface is aspherical; the third lens has a positive refracting power, and at least the lens surface of the object side is aspherical, at the central portion of the lens surface and the peripheral portion of the effective diameter a region having a positive refracting power stronger than the peripheral portion; a fourth lens having a positive refracting power and having a lens surface aspherical; a fifth lens having at least one lens surface 2 aspherical; and a sixth lens Since it has a positive refracting power and at least one of the 15 transparent surfaces is aspherical, it is known that the optical performance is still achieved while achieving wide angle and miniaturization. By arranging the first lens of the crucible on the most object side, the light incident at an angle can widen the angle of the optical system. I is the meniscus = a meniscus lens with a concave surface facing the imaging side, and good penetration of at least one side of the second lens into an aspherical surface corrects the aberrations while the two lenses are on-axis and off-axis. , the system is miniaturized. Since the first aspherical surface is advantageous for correcting the lens surface formation, the aberration is also relatively easy to correct the distortion. 20 M363171 5 15 It should be noted that the first lens also separates the on-axis and off-axis light, but as the first lens disposed on the most object side of the lens system, the material used is as follows. good. Further, in the lens system, the first lens is the lens having the largest diameter. Therefore, it is preferable to form the second lens to which the plastic material is applied to be aspherical in terms of lens manufacturing and aberration correction. By arranging the lens surface of the third lens shape on at least the object side to be aspherical, the central portion of the lens surface is convex, and has a positive refracting power between the peripheral portions of the central portion of the lens surface than the peripheral portion (four) The image is curved. The distance between the line distance and the length of the money is good. The == mirror and the sixth lens are all formed into a lens with at least one side of the aspherical refracting power. The at least one side of the fifth lens can be well The aperture system is arranged at the same time to miniaturize the lens system. 4 aberrations [Embodiment] Photography:: ===: A photographic lens to be created and a schematic view of a photographic apparatus using this structure = display lens.

It is easy to form. 20th M363171 2: The Abbe number of the material to the d line exceeds 45, then the correction of the chromatic aberration of magnification is difficult. ☆ 4S transparent, the material of the fifth lens U is the d line It is easier to correct the axial chromatic aberration well by using the Abe number 5^五二"V. However, if the Abbe number of the difference correction (four) material is more than 45, the axial chromatic aberration correction is better. Difficulty. As a material for forming the third lens L3 or the fifth lens L5, a polycarbonate resin manufactured by Teijin Chemicals Co., Ltd., (10) Bu (5) 6 (the product name of the company, "Panlite" is the company", and a refractive index...

The 20 M363171 5 photographic lens of this creation can only satisfy the conditional expression. The conditional expressions (1) to (8) are satisfied in the conditional expressions (1) to (8) as shown below. To two or more combinations of any one of (8).

The value 'the distance L' is a value other than the value of the post-intercept distance in the distance L distance value and the value of the post-intercept distance in the distance L distance value: the value obtained by adding the values indicated by the inter-bay length . 16 M363171

Then, the intercept distance Bf is the air-converted length from the first reading, A, or the lens R13 on the imaging side of the lens L0 to the imaging surface ri 6. Conditional expression (1): 2.0 <f45/f<5. 〇S aberration correction equation. - The lens system is configured to satisfy the conditional expression (1), and it is easy to correct the chromatic aberration and field curvature of 5 lines.

When the lens system is configured such that the value of f45 exceeds the conditional expression (f), that is, the conditional expression satisfying f45/f 2 5·〇, it is difficult to correct the color image well. If the lens system is configured such that the value of f45 is lower than the conditional expression 〇) The lower H) limit, that is, the conditional expression of 2.0 f45/f, makes it difficult to correct the curvature of field. The conditional expression (2): 2.5 < (D4 + D5) / f < 5_5 is an equation relating to the correction of the aberration or the size of the lens system.

The lens system is configured to satisfy the conditional expression (2), which can satisfactorily correct spherical aberration, distortion, and coma aberration, and since the back intercept distance is long, it can be used as a photographic lens while increasing the angle of view. Can get full optical performance. When the value of D4 + D5 exceeds the upper limit of conditional expression (2), the diameter of the lens surface on the object side of the first lens increases, and the overall length of the 20 mirror becomes long, which makes it difficult to be small. Chemical. When the lens system is configured such that the value of D4 + D5 is lower than the lower limit of conditional expression (2), spherical aberration and coma aberration can not be satisfactorily corrected, and it is difficult to form a bright lens having a small F value.

Rear cut 5 However, if the lens system is configured such that the value of milk exceeds the upper limit of the strip, it is difficult to satisfactorily correct the chromatic aberration of magnification. " If the lens system is constructed such that the value of f/f3 is lower than two: good enough to correct the chromatic aberration of color ‘but the second two is lower. It is difficult to insert various filters between the member 10 and the photographic lens 20. Equation condition (4): 7<L/f<14 is that the angle of view is related to the size of the device, and the lens system is configured to satisfy the conditional expression (), ^, θ ^ ^" from the small size and the field of view of the field of view Lens system. 1. However, if the lens system is configured such that the value of L/f exceeds the upper limit of the conditional expression 15, it is easy to achieve wide angle, but the lens system is increased in size. When the lens system is configured such that the value of L/f is lower than the lower limit of the conditional expression (4), the lens system and the system can be miniaturized, but it is difficult to achieve wide angle. φ Conditional formula (5): — 4.2 < f5/f < — 1〇 is a formula related to the parallax and axial chromatic aberration of the parachute. (1) The lens system is configured to satisfy the conditional expression (5), and it is possible to satisfactorily correct the chromatic aberration of magnification and the axial chromatic aberration. However, if the lens system is configured such that the value of f5/f exceeds the upper limit of the conditional expression (5), the chromatic aberration of magnification increases. 18 • M363171 If the lens system is configured such that the value of f5/f is lower than the lower limit of the conditional expression (5), the negative refracting power of the fifth lens becomes weak, and the axial chromatic aberration cannot be satisfactorily corrected. Conditional expression (6): 0.70<D4/f is an equation related to aberration correction. The 5 #foot conditional expression (6) can easily prevent the enlargement of the lens, the occurrence of aberrations, or the occurrence of ghosts. If the lower limit of the conditional expression (6) is exceeded, the chromatic aberration can be corrected well, but since the second lens L2 and the third lens u are too close, the lens side R4 and the third lens L3 on the imaging side of the second lens L2 The shape of the aspherical surface of the lens surface R5 on the object side is restricted, and thus the aberration correction is insufficient. Moreover, it is also possible to produce a ghost due to the reflection of the two lens faces r[] while the assembly becomes difficult.曰 is the equation for the axial chromatic aberration and the magnification chromatic condition (7): 1.5/vd4>vd5 difference. The 15^ lens I system is configured to satisfy the conditional expression (7), and the axial chromatic aberration and the chromatic aberration of magnification can be corrected. Also, the right lens system is constructed such that the value of vd4/vd5 is lower than the lower limit of the conditional expression, and it is difficult to simultaneously correct the axial chromatic aberration and the multiple conditional expression (8): 0.8<; Dl / fa Chule Laba aberration 0 20 formula. 丨矸疋 brother - lens impact resistance related to the lens system when used for vehicle use, etc. It is possible to increase the intensity of various impacts with the mirror.
