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, an eighth lens and a ninth lens. The first lens has refractive power and includes a convex surface facing the object side. The second lens has positive refractive power. The third lens has negative refractive power. The fourth lens has positive refractive power. The fifth lens has positive refractive power. The sixth lens has positive refractive power. The seventh lens has negative refractive power. The eighth lens element has refractive power and includes a convex surface facing the image side. The ninth lens has refractive power and includes a convex 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, the eighth lens and the ninth 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] The development trend of today's imaging lenses, in addition to the continuous development of miniaturization, with different application requirements, it is necessary to have the ability of small field of view, large aperture and high resolution. The known imaging lenses have been unable to meet today's needs. An imaging lens with another new architecture is required to meet the requirements of miniaturization, small field of view, large aperture and high resolution 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 field of view, The aperture is smaller and the resolution is higher, but still has good optical performance. [0004] The technical solution adopted by the present invention to solve the technical problem is to provide ...
