The ceramic reflector (ceramic cavity) is made from 99% Al2O3, and the body is fired at suitable temperature to retain appropriate porosity and high strength. The surface of the reflector is fully coated with high-reflectivity ceramic glaze. Compared with the gold-plated reflector, ceramic reflector has main advantages of extremely long service life and high diffuse reflectivity.
