Project Description

The semi-reflective lens is also called the laser cavity output mirror.

After the laser oscillates in the resonant cavity, the transflective lens exceeds the laser threshold, and the half mirror that has not reached the threshold is reflected back to the resonant cavity to continue to oscillate, thereby ensuring the quality and peak power of the laser light.

The surface of the film faces the concentrating cavity when installed. If white spots or colored spots appear on the semi-reflective lens, the film surface is damaged, which will affect the cutting speed and the cutting thickness, and must be replaced immediately.
