Custom Shape Alumina Ceramic Laser Cavity Reflector | High Reflectivity
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.Main Physical Characteristics

Working Temperature
Glazed: It is best not to keep the working temperature of glazed ceramic reflectors above 300℃ for a long time, otherwise crystallization may occur.
Non glazed: The working temperature of non glazed ceramic reflectors can be 1200℃.
