Abstract

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

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 large aperture and high resolution, requires the ability to resist environmental temperature changes with different application requirements. The known imaging lenses have been unable to meet today's needs. There is another imaging lens with a new architecture to meet the needs of large aperture, 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 smaller aperture value and higher resolution in view of the defect that the imaging lens in the prior art cannot simultaneously meet the requirements of large aperture, high resolution and resistance to changes in ambient temperature. High, resistant to ambient temperature ...
