Problems solved by technology

[0005] In order to solve the existing detection lens IR (optical color filter) wavelength in the background technology is determined by the actual image shot by the electronic module (CCD or COMS). In the actual detection process, the efficiency is relatively low and the detection process is cumbersome and complicated. It is easy to cause misjudgment and affect the technical problem of detection efficiency. This invention proposes a lens IR wavelength detection equipment. The invention has simple operation steps, greatly improves work efficiency, ensures the quality of the finished lens, and detects the IR wavelength timely and accurately. and determine if there is a mix of IR with different wavelengths
