Abstract

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

Description

technical field [0001] The invention relates to an imaging lens. Background technique [0002] The development trend of today's imaging lenses, in addition to the continuous development towards large apertures, with different application requirements, it is also necessary to have the characteristics of high resolution and resistance to environmental temperature changes. The existing imaging lenses can no longer meet today's needs. There is another imaging lens with a new structure to meet the needs of large aperture, high resolution and resistance to environmental temperature changes at the same time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an imaging lens with a small aperture value and a high High, resistant to environmental temperature changes, but still has good optical properties. [0004] The technical solution adopted by the present invention to solve the technical problem is to provide an imagin...
