Sapphire Substrate Sapphire Substrate makes for superior window material for many IR applications from 3µm to 5µm, for they offer resistant to high temperature, thermal shock, water and sand erosion, small dielectric loss, excellent electrical insulation, with important mechanical and chemical characteristics, and scratching. We have C-Plane R-Plane Sapphire Substrates. C-plane sapphire substrates used for developing III-V and II-VI compounds like GaN for blue LED and laser diodes.
