Abstract

The invention relates to a divisional application with an application number of 201910010426.8. The embodiment of the invention discloses a high-pixel wide-angle day and night confocal camera module.The module at least comprises an optical lens, a high-pixel wide-angle day-night confocal optical system is installed in the optical lens, and the optical system sequentially comprises a first lens, asecond lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens from an object plane to an image plane along an optical axis; the object plane side of the first lens is a convex surface, and the image plane side is a concave surface; the object plane side of the second lens is a concave surface, and the image plane side is a convex surface; the object planeside of the third lens is a convex surface; 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 plane sideof the seventh lens is a concave surface, and the image plane side is a convex surface; the eighth lens is a biconvex lens. The optical system or the camera module is mainly composed of eight lenses,the number of the lenses is reasonable, the structure is simple, and good optical performance is achieved.

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 a camera module, in particular to a high-pixel wide-angle day-night confocal camera module. 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] In o...
