4inch C-axis sapphire wafer for epi-ready, Al2O3 single crystal
wafer ,sapphire thick glass lens for covering,sapphire optical
windows, A plane,
R plane, C plane, M plane and other random plane for sapphire
crystal
Sapphire is one of the hardest materials, and possesses very good
transmission during the range of
visible and near IR spectrum.
It is widely used as optical window in infrared and far infrared
military equipments, apparatus and
instruments of satellite and space technology, and navigation and
spaceflight, such as night infrared
scope/sight and night vision camera, etc.The sapphire crystal
window is intensively applied in high-
tech fields.
