Abstract

The invention is suitable for the technical field of optical detection, and provides a lens performance test system, which comprises a light source emission module, an incidence position control module, an optical screen, a light source detection module, a lens fixing module and an upper computer; the light source emission module emits laser to the light screen, the light screen reflects the laser, the laser reflected by the light screen is focused by a target lens and then received by the light source detection module, and the light source detection module sends light energy information of the received laser to the upper computer; the upper computer changes the incidence position of the laser on the optical screen through the incidence position control module, receives light energy information sent by the light source detection module at different incidence positions, and determines performance parameters of the target lens according to the light energy information. The lens performance test system can automatically and efficiently test the performance of the lens, and has very high accuracy.

Description

technical field [0001] The invention belongs to the technical field of optical detection, in particular to a lens performance testing system. Background technique [0002] Lens is an optical component made of transparent material, which is widely used in various fields such as lidar and 3D imaging. [0003] However, due to the influence of manufacturing process, materials and other factors, the performance of each lens is different. In actual production, if the product is made with a lens with substandard performance, the yield rate of the product will be greatly affected. Therefore, the performance of the lens can be checked. Automatic and efficient testing is of great significance to actual production. [0004] The inventors of the present application found that the traditional method of testing lens performance by using separate optical paths has low efficiency and large errors, and is not suitable for use in mass production. Contents of the invention [0005] In view...
