Sapphire & windows are applied as circuit substrates, epitaxial substrates, substrates, oriented substrates to GaN,GaAs. And other, Sapphire possesses nice light transmission in 0.20 ~ 5.50um 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.

These sapphire substrates & windows contain two types, Sapphire windows, Elliptic windows,
