SAPPHIRE SUBSTRATES & WINDOWS

Sapphire Substrates & windows are applied as circuit substrates, epitaxial substrates, substrates, oiented substrates to GaN,GaAs. And other, Sapphire possesses nice light transmission in 0.20 ~ 5.50μm wave band, and the infrared ray transmission is hardly influenced by temperature, so the optical components made of sapphire are fully applied to military infrared equipment, observation window for high temperature furnaces, windows for counters, etc.
