The ceramic reflector is used 99% Al2O3 content which is sintered at the proper temperatures to achieve a controlled porosity and strength. The surface of the ceramic reflector is coated with high reflectance reflectivity ceramic glaze.Compared with gold-plated reflector, the biggest advantage is its extremely long life time and diffuse reflection characteristics.
Main features:
1. Full glazed surface to achieve maximize reflectance efficiency and easy to clean
2. 97% reflectance efficiency at the wavelength of 600-1000nm
3. Reflectivity efficiency exceeds 95% across the wavelength range 400-1200nm
4.with appropriate porous and high strength characteristics
