Problems solved by technology

[0002] The lens is an important part of the vehicle camera. At present, the vehicle lens market is in a stage of rapid development. There are endless vehicle lenses on the market, but most of the lenses have problems such as small light transmission and poor edge image quality due to their large field of view. Vehicle lenses have high requirements on the working temperature range, many lenses cannot pass the high and low temperature test, and the image quality is seriously degraded

Abstract

The invention relates to a 3-mm high-resolution prime lens and an imaging method thereof. The 3-mm high-resolution prime lens comprises a front group A of which the focal power is negative, a diaphragm C and a rear group B of which the focal power is positive which are arranged in sequence from object space to image space, wherein the front group A comprises a meniscus negative lens A1, a biconcave negative lens A2 and a biconvex positive lens A3 which are arranged in sequence, and the rear group B comprises a bonding group composed of a meniscus negative lens B1 and a biconvex positive lens B2 which are arranged in sequence. The lens has the advantages that the structure is simple, the design is reasonable, the field angle is large, processing is easy, and the resolution ratio is high.

Description

technical field [0001] The invention relates to a 3mm high-resolution fixed-focus lens and an imaging method. Background technique [0002] The lens is an important part of the vehicle camera. At present, the vehicle lens market is in a stage of rapid development. There are endless vehicle lenses on the market, but most of the lenses have problems such as small light transmission and poor edge image quality due to their large field of view. Vehicle lenses have high requirements on the working temperature range, and many lenses cannot pass the high and low temperature test, and the image quality is seriously degraded. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a 3mm high-resolution fixed-focus lens and an imaging method. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a 3mm high-resolution fix...
