1. Description For Sapphire
Sapphire is made from 99.999％ Al2O3 and is one of the hardest materials, it possesses
very good transmission during the range ofvisible and near IR spectrum. so 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 wavelength of worldhawk general windows substrate(without coating)
