Abstract

An imaging lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens. The first lens is a meniscus lens with negative refractive power, and comprises a convex surface facing the object side and a concave surface facing the image side. The second lens has negative refractive power. The third lens element has refractive power. The fourth lens has positive refractive power. The fifth lens has positive refractive power and comprises a convex surface facing the image side. The sixth lens has refractive power. The seventh lens has positive refractive power. The eighth lens has negative refractive power and comprises a concave surface facing the object side. The first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens and the eighth lens are sequentially arranged from the object side to the image side along the optical axis.

Description

technical field [0001] The present invention relates to an imaging lens. Background technique [0002] In addition to the development trend of today's imaging lenses, in addition to the continuous development of miniaturization and high resolution, with different application requirements, it is also necessary to have the ability to resist environmental temperature changes. There is another imaging lens with a new architecture to meet the requirements of miniaturization, high resolution and resistance to environmental temperature changes at the same time. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an imaging lens with a short overall length of the lens, a small aperture, Smaller values, higher resolution, and resistance to ambient temperature changes, but still have good optical performance. [0004] The technical solution adopted by the present invention to solve the technical problem is to provide an imagi...
