Problems solved by technology

[0003] 1) The pixel requirements of the camera are getting higher and higher, and the size of the chip is also increasing accordingly, resulting in an increase in the size of the entire lens. For some applications with limited installation positions, such as vehicle front-view lenses, because they need to be installed in The inner side of the windshield, there is a risk of interference with the windshield, and a special lens design is required to achieve the small size requirement

Abstract

The invention discloses an optical lens. The optical lens sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object side to an imageside along an optical axis; the first lens can have positive focal power, wherein the object side surface of the first lens is convex, and the image side surface of the first lens is concave; the second lens can have negative focal power, wherein the object side surface of the second lens is concave, and the image side surface of the second lens is convex; the third lens can have positive focal power, wherein the object side surface of the third lens is concave, and the image side surface of the third lens is convex; the fourth lens can have positive focal power, wherein the object side surface and the image side surface of the fourth lens are both convex; the fifth lens can have positive focal power, wherein the object side surface of the fifth lens is convex, and the image side surfaceof the fifth lens is concave; and the sixth lens can have negative focal power, wherein the object side surface of the sixth lens is convex, and the image side surface of the sixth lens is concave. According to the optical lens, at least one of the beneficial effects of miniaturization, high pixel, large aperture and the like can be realized.

Description

technical field [0001] The present application relates to an optical lens, and more particularly, the present application relates to an optical lens including six lenses. Background technique [0002] In recent years, the advanced driver assistance system (Advanced Driver Assistance Systems, ADAS) market has grown rapidly. As an important part of the vehicle lens, the performance requirements are more stringent, which is mainly reflected in the following two aspects: [0003] 1) The pixel requirements of the camera are getting higher and higher, and the size of the chip is also increasing accordingly, resulting in an increase in the size of the entire lens. For some applications with limited installation positions, such as vehicle front-view lenses, because they need to be installed in The inner side of the windshield, there is a risk of interference with the windshield, and a special lens design is required to achieve the small size requirement. The length of such existing...
