Abstract

This application is a divisional application with application number 201910010426.8. The embodiment of the present invention discloses a high-pixel wide-angle day-night confocal optical system, which sequentially includes: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a Six lenses, the seventh lens and the eighth lens; the object plane side of the first lens is convex, and the image plane side is concave; the object plane side of the second lens is concave, and the image plane side is convex; the object plane side of the third lens The fourth lens is a biconcave lens; the image surface side of the fifth lens is a convex surface; the sixth lens is a biconvex lens; the object surface side of the seventh lens is concave, and the image surface side is a convex surface; the eighth lens is a biconvex lens. The optical system of the embodiment of the present invention is mainly composed of 8 lenses, the number of lenses is reasonable, the structure is simple, and it has good optical performance.

Description

[0001] This application is a divisional application, the application number of the original application is 201910010426.8, the application date is January 07, 2019, and the title of the invention is "high-pixel wide-angle day and night confocal optical system and camera module for its application". Technical field: [0002] The invention relates to an optical system, in particular to a high-pixel wide-angle day-night confocal optical system. Background technique: [0003] With the development of science and technology, the high-pixel wide-angle day and night confocal optical system or camera module can observe a wider spatial range due to its large viewing angle, and at the same time, the day and night confocal characteristics can ensure that it can be used in both day and night conditions. It can work effectively, so it is widely used in the field of automobiles and assisted driving. But it has many lens pieces and lack of complex structure. Invention content: [0004] I...
