Test equipment of wide-angle lens module and application of test equipment

Abstract

The invention provides test equipment of a wide-angle lens module and an application of the test equipment. A 1200*900mm uniform light source is selected by the equipment; the test equipment is suitable for a module test within a range of 94-165 degrees; distortion caused by a large field angle is compensated through an anti-distortive target; and for the module with a relatively large focusing distance, the measured distance is reduced through a 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.
