Abstract

The invention provides a low distortion optical system which at least comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens in order from an object plane to an image plane along an optical axis. The first lens has a convex object plane side, a concave image plane side and negative focal power. The second lens is a biconvex lens with positive focal power. The third lens is a biconcave lens with negative focal power. The fourth lens is a biconvex lens with positive focal power. The fifth lens is a biconvex lens with positive focal power. The sixth lens has a concave object plane side, a plane image plane side and negative focal power. The invention further provides the lenses. The low distortion optical system provided by the invention is applied to intelligent auxiliary driving systems such as a track offset system and other equipment, consists of six different lenses in intercombination, has the advantages of less lenses, simple structure and small size, and has low distortion, high pixel and other good optical properties.

Description

Technical field: [0001] The invention relates to an optical system and a lens applied thereto, in particular to a low-distortion optical system applied to equipment such as a vehicle intelligent auxiliary driving system such as a track offset system and an applied lens thereof. Background technique: [0002] Existing optical systems or lenses, especially optical systems or lenses used in automotive intelligent assisted driving systems such as track offset systems, have defects of complex structures. Invention content: [0003] In order to overcome the problems of existing optical systems or lenses with a large number of lenses and complex structures, the embodiments of the present invention provide a low-distortion optical system on the one hand. [0004] A low-distortion optical system, which sequentially includes at least a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens along the optical axis from the object plane to the image plan...
