[0002] Lenses can be widely used in security, automotive, digital cameras, lasers, optical instruments and other fields. With the continuous development of the market, lens technology is becoming more and more widely used. As the scope of lens application becomes larger and larger, the demand for lenses is also increasing, resulting in each step before being put into use to be more efficient. Testing, as a very important step, needs to be fast and accurate.

[0003] When using the existing infrared lens testing device, the testing instrument and the workbench are relatively fixed, which makes the device less flexible. In addition, due to the single fixture, the type of infrared lens tested is often only applicable to one shape, and the fixing device for the infrared lens is often only applicable to infrared lenses of the same size, which further reduces the scope of application and brings certain adverse effects to people's use process. Therefore, we propose a testing device for infrared lenses. Utility Model Content
