Wide-angle lens module test equipment and its application

Abstract

A wide-angle lens module testing equipment and its application. The equipment selects a large uniform light source of 1200x900mm, which is suitable for module testing in the range of 94°-165°, and through the anti-distortion target plate, the distortion caused by the large field of view is compensated. For For modules with a larger focusing distance, the measured distance can be reduced through the teleconverter.

Description

technical field [0001] The invention relates to a test device for a camera module, in particular to a test device for a wide-angle lens module and its application. Background technique [0002] With the rapid development of science and technology, the development of various electronic products, and with the development of mobile Internet and the increasing of multimedia information equipment, more and more products or equipment have continuously increased demand for electronic and optical products and parts quality specifications, so The production efficiency and quality requirements for various processes are also gradually increasing. In particular, products that use lens designs in combination with various products are also produced in response to various needs. Therefore, the development of the lens is also an important subject. Basically, there are general classifications for the use of lenses: standard lenses, wide-angle lenses, telephoto lenses, and fisheye lenses. ...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to provide a wide-angle lens module testing equipment, which is suitable for the detection and focusing test of wide-angle lens modules, so as to solve problems such as overexposure and unevenness of brightness and inconvenience of focusing during detection.
