1. Description For Sapphire
High Crystal Purity:> 99.995% Al2O3
Crystal orientation: Provide A plane, R plane, C plane, M plane and
other random plane
for sapphire crystal product.
Sapphire is one of the hardest materials, and possesses very good transmission during the range
ofvisible and near IR spectrum ,good heat dissipating capacity,9.0 Hardness.
It is widely used as led epi-ready
wafer, 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.
