The eight lenses are arranged in order from an object side to an image side along an optical axis.
In an exemplary embodiment, the image side surface of the second lens is concave; the image side surface of the fifth lens is a convex surface; the object side surface of the sixth lens is a concave surface and the image side surface of the sixth lens is a convex surface; the object side surface of the seventh lens is a convex surface and the image side surface of the seventh lens is a concave surface; and the focal power of the eighth lens is negative focal power.
In an exemplary embodiment, the profile of each lens may be further defined as follows: the object side surface of the first lens is a convex surface, and the image side surface of the first lens is a concave surface; the object side surface of the second lens is a convex surface; the image side surface of the third lens is a concave surface; and/or the object side surface of the eighth lens element is convex and the image side surface of the eighth lens element is concave.

SAG82/CT 8. ltoreq.1.66. Through adjusting the relation between rise and the thickness of this lens, can adjust optical imaging lens's chief ray angle, and then can effectively improve optical imaging lens's relative luminance, promote image plane definition.
In an exemplary embodiment, the central thickness CT3 of the third lens and the central thickness CT4 of the fourth lens may satisfy the following relationship: 0.5. ltoreq. CT3/CT 4. ltoreq.1.0, more specifically 0.68. ltoreq. CT3/CT 4. ltoreq.1.0. Through the central thickness of rational distribution third lens and fourth lens, can promote optical imaging lens to the balanced ability of coma.

By reasonably controlling the ratio of TTL to ImgH, the size of the optical imaging lens can be effectively compressed, so that the ultrathin characteristic of the lens is ensured, and the requirement for miniaturization of an imaging device is met.
In an exemplary embodiment, the effective focal length f8 of the eighth lens and the center thickness CT8 of the eighth lens may satisfy the following relationship: 9.0< | f8/CT8| <13.0, more specifically, 10.03 ≦ f8/CT8| ≦ 12.10.

By configuring a smaller F number, the light transmission amount can be increased, so that the optical imaging lens has the advantage of a large aperture, and the imaging effect in a dark environment can be enhanced while the aberration of the marginal field of view can be reduced.
In one embodiment, the effective focal length f of the optical imaging lens and the radius of curvature R1 of the object side surface of the first lens may satisfy the following relationship: 2.0< f/R1<2.5, more specifically 2.14 ≦ f/R1 ≦ 2.26. Through the curvature radius of rationally setting up first lens, can balance the aberration more easily, promote optical imaging lens's imaging performance.

Through the curvature radius of the object side surface and the image side surface of the eighth lens, the optical imaging lens can be better matched with the chief ray angle of the photosensitive chip at the rear end of the optical imaging lens.
In one embodiment, the effective focal length f8 of the eighth lens and the radius of curvature R16 of the image-side surface of the eighth lens may satisfy the following relationship: -3.0< f8/R16< -2.0, more particularly-2.33. ltoreq. f 8/R16. ltoreq. 2.27. The curvature radius of the eighth lens is reasonably set, so that the optical imaging lens has better astigmatism balancing capability.
In one embodiment, the effective focal length f of the optical imaging lens, the effective focal length f1 of the first lens and the effective focal length f2 of the second lens may satisfy the following relationship: 0.5< | f/f1| + | f/f2| <1.5, more specifically, 0.84 ≦ f/f1| + | f/f2| ≦ 1.39. The effective focal lengths of the first lens and the second lens are reasonably distributed, so that the deflection angle of light can be reduced, and the sensitivity of the optical imaging lens is reduced.
In one embodiment, the effective focal length f of the optical imaging lens and the effective focal length f8 of the eighth lens may satisfy the following relationship: 1.0< | f/f8| <1.5, more specifically, 1.05 ≦ f/f8| ≦ 1.19. By reasonably selecting the effective focal length of the eighth lens, the optical imaging lens has better capacity of balancing field curvature.
In one embodiment, the air interval T45 of the fourth lens and the fifth lens on the optical axis and the air interval T67 of the sixth lens and the seventh lens on the optical axis may satisfy the following relationship: 0.5< T45/T67<1.5, more specifically 0.79 ≦ T45/T67 ≦ 1.35. By reasonably controlling the ratio of the air interval of the fourth lens and the fifth lens on the optical axis to the air interval of the sixth lens and the seventh lens on the optical axis, the optical imaging lens can have better capability of balancing dispersion and distortion.
In one embodiment, the effective focal length f of the optical imaging lens and the radius of curvature R16 of the image-side surface of the eighth lens may satisfy the following relationship: 2.0< f/R16<3.0, more specifically 2.45 ≦ f/R16 ≦ 2.72. The optical imaging lens can be easily matched with a common photosensitive chip by reasonably setting the relation between the curvature radiuses of the image side surfaces of the optical imaging lens and the eighth lens.
In one embodiment, the center thickness CT4 of the fourth lens and the air space T45 of the fourth lens and the fifth lens on the optical axis may satisfy the following relationship: 2.5< CT4/T45<5.5, more specifically 2.96 ≦ CT4/T45 ≦ 5.22. By reasonably controlling the ratio of the central thickness of the fourth lens to the air interval of the fourth lens and the fifth lens on the optical axis, the optical imaging lens can have better capability of balancing field curvature and dispersion.
In an exemplary embodiment, the optical imaging lens may further include at least one stop to improve the imaging quality of the lens. For example, a diaphragm may be disposed at the first lens.
Optionally, the optical imaging lens may further include a filter for correcting color deviation and/or a protective glass for protecting a photosensitive element on the imaging surface.
The optical imaging lens according to the above-described embodiment of the present application may employ a plurality of lenses, for example, eight 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 volume of the lens can be effectively reduced, the sensitivity of the lens can be reduced, and the machinability of the lens can be improved, so that the optical imaging lens is more beneficial to production and processing and can be suitable for portable electronic products. Meanwhile, the optical imaging lens with the configuration has the advantages of being ultrathin, small in size, large in aperture, high in imaging quality and the like.
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 of the lens to the periphery of the lens. Unlike a spherical lens having a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has better curvature radius characteristics, and has advantages of improving distortion aberration and improving astigmatic aberration. After the aspheric lens is adopted, the aberration generated during imaging can be eliminated as much as possible, thereby improving the imaging quality.
However, it will be appreciated by those skilled in the art that the number of lenses constituting an optical imaging lens 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 eight lenses are exemplified in the embodiment, the optical imaging lens is not limited to include eight lenses. 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.
