Abstract

An embodiment of the invention discloses a high-resolution wide-angle infrared optical system which, from the object plane to the image plane along the optimal axis, sequentially comprises: a first lens, a second lens, a third lens, a fourth lens and a fifth lens, wherein the image plane side of the first lens is a concave surface with negative focal power; the object plane side of the second lensis a convex surface while the image plane side is a concave surface with positive focal power; the image plane side of the third lens is a convex surface with positive focal power; the object plane side of the fourth lens is a concave surface while the image plane side is a convex surface with positive focal power; the object plane side of the fifth lens is a convex surface while the image planeside is a concave surface with positive focal power. Furthermore, the embodiment of the invention also provides a camera module. The optical system and camera module provided by the embodiment of theinvention are mainly composed of just five lenses, and thus the structure is simple; through combination of different lenses and reasonable distribution of focal power, the high-resolution wide-angleinfrared optical system has good performance such as large aperture, large view angle, high resolution and perfect athermalization.

Description

Technical field: [0001] The invention relates to an optical system and a camera module for its application, in particular to a high-pixel wide-angle infrared optical system and a camera module for its application. Background technique: [0002] With the application of infrared imaging technology and the development of intelligent driving assistance systems, infrared lenses are more and more widely used in the vehicle field.
