Problems solved by technology

[0003] As the camera module develops towards thinner and shorter, the height of the camera module is compressed. Therefore, the number and size of the mechanism parts inside the camera module are also relatively compressed and reduced, making the mechanism originally used to block glare or eliminate glare Parts cannot be placed, making flare easily generated inside the lens

Abstract

The invention provides a device for testing the glare of a lens module, which is used for testing glare condition in the lens module and comprises: a pedestal which comprises a bearing platform, wherein the bearing platform is provided with an accommodating through hole used for holding the lens module to be tested; an optical amplifying unit fixed above the pedestal, wherein the optical axis ofthe optical amplifying unit and the central line of the holding through hole are arranged on the same straight line, and the optical amplifying unit is used for observing the lens module; a circular arc-shaped slide rail arranged opposite to the pedestal, wherein the circle center of the circular arc-shaped slide rail coincides with the center of the holding through hole on the bearing platform; and a light source which is arranged on the circular arc-shaped slide rail and capable of sliding along the circular arc-shaped slide rail. The invention also provides a method for testing the glare of the lens module.

Description

technical field [0001] The invention relates to a glare detection device and a detection method, in particular to a lens module glare detection device and a detection method thereof. Background technique [0002] In recent years, with the development of optical products, the scope of application of lens modules continues to expand, such as digital cameras, mobile phones with camera functions and other electronic products. For electronic products, especially consumer electronic products, the development trend is light weight and thinner, and the corresponding lens modules installed therein are also becoming smaller and smaller, and the requirements for precision are also getting higher and higher. [0003] As the camera module develops towards thinner and shorter, the height of the camera module is compressed. Therefore, the number and size of the mechanism parts inside the camera module are also relatively compressed and reduced, making the mechanism originally used to block...
