Tianjin QM Optics Co., Ltd.

The ceramic laser cavity reflector body is prepared by doping 99% Al2O3, and the body is fired at an appropriate temperature to retain appropriate porosity and strength. The surface of the reflector adopts a fully glazed high reflectivity ceramic glaze process, which has the biggest advantage over gold-plated reflectors in terms of its long service life and diffuse reflection characteristics. We have the capability to custom design and manufacture the alumina ceramic laser cavity reflector. The product is in high precision, high reflectivity and long service life.
