The object-side surface of the third lens element can be convex at paraxial region, and the image-side surface thereof can be concave at paraxial region and can have at least one inflection point, thereby facilitating the convergence of peripheral light rays with large viewing angle on the image plane and avoiding the problem of image formation or manufacture caused by too much curvature of the surface around the image plane.
The fourth lens element, the fifth lens element, the sixth lens element and the seventh lens element respectively have positive refractive power or negative refractive power, and refractive power distribution of the optical imaging lens can be configured appropriately, so that aberration can be corrected and the field angle can be enlarged. The seventh lens element has a convex object-side surface at a paraxial region and a concave image-side surface at a paraxial region thereof, and has a change from convex to concave from the paraxial region to the peripheral region thereof, and has a change from concave to convex from the paraxial region to the peripheral region thereof, thereby facilitating correction of high-order aberration of the optical imaging lens and improving the resolving power thereof to obtain good imaging quality.
The eighth lens element with negative refractive power has a concave image-side surface at paraxial region, which is helpful for making the principal point of the optical imaging lens effectively away from the image-side surface to enhance the reduction of the back focal length thereof, thereby reducing the total track length of the optical imaging lens and achieving the purpose of miniaturization; in addition, the image side surface of the eighth lens element has at least one inflection point, which can effectively suppress the angle of the light rays of the off-axis field incident on the image sensor, and preferably correct the aberration of the off-axis field.
By reasonably controlling the positive and negative distribution of the refractive power of each lens in the imaging lens, the low-order aberration of a control system can be effectively balanced, the tolerance sensitivity of the system can be reduced, and the miniaturization of the imaging lens is favorably ensured.

Therefore, the surface shape of the second lens can be adjusted to correct off-axis aberration, and light rays can have proper incident and emergent angles on the second lens, so that the area of an imaging surface is increased, and the outer diameter of a lens at the front end of a lens is reduced.
It should be noted that the refractive power refers to the refractive power of the optical system for reflecting the incident parallel light beam. The optical system has positive refractive power, which indicates that the refraction of the light rays is convergent; the optical system has negative refractive power, indicating that the refraction of light is divergent. In the optical imaging lens system provided by the present invention, if the refractive power or the focal length of the lens element does not define the position of the region, it means that the refractive power or the focal length of the lens element can be the refractive power or the focal length of the lens element at the paraxial region.
For each lens arrangement in the optical imaging lens, in a case of from left to right from an object side to an image side, a convex object side of the lens means that any point on a passing surface of the object side of the lens is a tangent plane, the surface is always on the right of the tangent plane, and the curvature radius of the surface is positive, otherwise, the object side of the lens is a concave surface, and the curvature radius of the surface is negative. The image side surface of the lens is convex, which means that any point on the passing surface of the image side surface of the lens is tangent, the surface is always on the left side of the tangent plane, the curvature radius is negative, otherwise, the image side surface is concave, and the curvature radius is positive. If a section is made through any point on the object-side or image-side surface of the lens, the surface has both a portion to the left of the section and a portion to the right of the section, and the surface has points of inflection. The above applies to the determination of the presence of irregularities at the paraxial region of the object-side surface and the image-side surface of the lens. In the optical imaging lens provided by the invention, if the lens surface is a convex surface and the position of the convex surface is not defined, the convex surface can be positioned at the position of the lens surface close to the optical axis; if the lens surface is concave and the position of the concave surface is not defined, it means that the concave surface can be located at the position of the lens surface near the optical axis.
In the optical imaging lens disclosed by the invention, the lens can be made of plastic, and when the lens is made of plastic, the production cost can be effectively reduced. In addition, the object-side surface and the image-side surface of each lens can be Aspheric Surfaces (ASP), the ASP can be easily manufactured into shapes other than spherical surfaces, more control variables are obtained to reduce aberration, and the number of the lenses is further reduced, so that the total length of the optical imaging lens can be effectively reduced.
In addition, in the optical imaging lens, at least one diaphragm can be arranged according to requirements so as to reduce stray light and be beneficial to improving the imaging quality. In the present invention, the aperture configuration may be a front aperture, i.e., the aperture is disposed between the subject and the first lens. The front arrangement of the aperture can enable the exit pupil of the optical imaging lens to generate a longer distance with the imaging surface, so that the optical imaging lens has a telecentric effect, and the efficiency of receiving images by a CCD or a CMOS of the electronic photosensitive element can be increased.
The optical imaging lens of the present invention will be described in detail with reference to specific embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
