High-definition wide-angle optical system and camera module for its application

Abstract

The embodiment of the present invention discloses a high-definition wide-angle optical system, which is sequentially arranged along the optical axis from the object plane to the image plane: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens; Among them, the fifth lens and the sixth lens are cemented together to form a combined lens, and satisfy TTL / f≤7.5, where TTL is the distance from the apex of the first lens on the object side of the optical system to the imaging surface, and f is the distance of the entire optical system focal length. On the other hand, the embodiment of the present invention also provides a camera module. The embodiment of the present invention is mainly composed of six lenses, the number of lenses is small, and the structure is simple; the combination of different lenses makes the distribution of optical power reasonable, and the fifth lens and the sixth lens are cemented lenses, so that the present invention has a large aperture , high pixel, low distortion and good heat dissipation and other optical properties.

Description

High-definition wide-angle optical system and its application camera module Technical field: The present invention relates to a kind of camera module of optical system and application thereof, especially a kind of high-resolution lens that is made up of six lenses. Clear wide-angle optical system and its application vehicle camera module. Background technique: [0002] With the application and popularization of the vehicle safety driving system, the vehicle camera module has also been widely used. while applying The camera module for in-vehicle security monitoring is required to be able to adapt to clear images in both day and night environments, so the camera module needs to Infrared confocal day and night should be considered; at the same time, in order to meet the detailed identification of passengers in the car, the camera module needs to have a high resolution clarity. In order to meet the above requirements, the existing optical systems or camera modules genera...
