[ detailed description ] embodiments
The invention is further described with reference to the following figures and embodiments.
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present invention in its various embodiments. However, the technical solution claimed in the present invention can be implemented without these technical details and various changes and modifications based on the following embodiments.
The following is an embodiment one:
referring to fig. 1 to 4, an imaging optical lens 10 according to a first embodiment of the present invention is provided. In fig. 1, the left side is an object side, and the right side is an image side, the imaging optical lens system 10 mainly includes five coaxially disposed lenses, namely, a first lens L1, a second lens L2, a third lens L3, a fourth lens L4 and a fifth lens L5 in order from the object side to the image side. A stop S1 is further provided on the object-side surface of the first lens L1, and a glass plate GF is provided between the fifth lens L5 and the image plane Si, where the glass plate GF may be a glass cover plate or an optical filter.
In this embodiment, the first lens element L1 with positive refractive power has a convex object-side surface and a planar image-side surface; the second lens element L2 with negative refractive power has a planar object-side surface and a concave image-side surface; the third lens element L3 with positive refractive power has a concave object-side surface and a convex image-side surface; the fourth lens element L4 with positive refractive power has a concave object-side surface and a convex image-side surface; the fifth lens element L5 with negative refractive power has a concave object-side surface and a convex image-side surface.
The focal length of the entire imaging optical lens 10 is f in millimeters (mm), the focal length of the first lens L1 is f1 in millimeters (mm), the focal length of the third lens L3 is f3 in millimeters (mm), the radius of curvature of the image-side surface of the second lens L2 is R2, the radius of curvature of the object-side surface of the fifth lens L5 is R9, and the radius of curvature of the image-side surface of the fifth lens L5 is R10. f. f1, f3, R2, R9 and R10 satisfy the following relationships:
5.10≤R2/f≤5.20 (1)
3.40≤R9/R10≤3.50 (2)
8.30≤(f1+f3)/f≤8.50 (3)
the shape and refractive power of the first lens L1 are defined by the conditional expression (1), and the degree of deflection of the light rays passing through the imaging optical lens can be reduced within the range defined by the conditional expression (1), thereby effectively reducing aberrations.
The conditional expression (2) defines the shape of the fifth lens L5, and within the range defined by the conditional expression (2), the degree of deflection of the light rays passing through the imaging optical lens can be reduced, and aberration can be effectively reduced.
The conditional expression (3) specifies the ratio of the sum of the focal length of the first lens L1 and the focal length of the third lens L3 to the focal length of the image pickup optical lens, and within the range specified by the conditional expression (3), the focal powers of the first lens L1 and the third lens L3 can be effectively distributed to correct the aberration of the image pickup optical lens, thereby improving the image quality.
In the present embodiment, the focal length of the second lens L2 is f2, the focal length of the fifth lens L5 is f5, and f2, f5, and f satisfy the following relations:
-2.00≤(f2+f5)/f≤-1.90 (4)
the conditional expression (4) specifies the ratio of the sum of the focal length of the second lens L2 and the focal length of the fifth lens L5 to the focal length of the image-taking optical lens, and within the range specified by the conditional expression (4), the focal powers of the second lens L2 and the fifth lens L5 can be effectively distributed to correct the aberration of the image-taking optical lens 10, thereby improving the image quality.
In the present embodiment, the focal length f3 of the third lens L3 and the focal length f of the entire imaging optical lens satisfy the following relationship:
3.77≤f3/f≤11.46 (5)
when f3/f satisfies the conditional expression (5), the focal power of the third lens L3 can be effectively distributed, and the aberration of the image pickup optical lens is corrected, thereby improving the imaging quality.
In addition, the radius of curvature of the object-side surface of the third lens L3 is R5, the radius of curvature of the image-side surface of the third lens L3 is R6, and R5 and R6 satisfy the following relational expressions:
-14.97≤(R5+R6)/(R5-R6)≤-4.35 (6)
conditional expression (6) specifies the shape of the third lens L3, and within the range specified by conditional expression (6), the degree of deflection of the light rays passing through the imaging optical lens can be reduced, and aberration can be effectively reduced.
In addition, in the imaging optical lens 10 provided in the present embodiment, the surface of each lens can be an aspheric surface, which is easy to be made into a shape other than a spherical surface, so as to obtain more control variables for reducing the aberration and further reducing the number of lenses used, thereby effectively reducing the total length of the imaging optical lens 10. In the present embodiment, both the object-side surface and the image-side surface of each lens are aspheric.
It is to be noted that since the first lens L1, the second lens L2, the third lens L3, the fourth lens L4, and the fifth lens L5 have the structure and the parameter relationship as described above, the image-taking optical lens 10 can reasonably distribute the power, the interval, and the shape of each lens, and thus correct various kinds of aberrations.
In the present embodiment: TTL/IH is equal to or less than 1.44, and FNO is equal to or less than 2.07, where TTL is the optical length of the image pickup optical lens 10, IH is the image height of the image pickup optical lens 10, and FNO is the focal number, i.e., the ratio of the effective focal length to the entrance pupil aperture. In this way, the imaging optical lens 10 can satisfy design requirements for a large aperture and an ultra-thin structure while having good optical imaging performance.
In addition, at least one of the object-side surface and the image-side surface of each lens may further have an inflection point and/or a stagnation point, so as to meet the requirement of high-quality imaging.
