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 wafercrystal window is intensively applied in high-tech fields.
Sapphire optical windows are ideal for applications where high pressure, vacuum, or corrosive atmospheres are a consideration. Sapphire, a single crystal form of Al2O3, is resistant to attack by strong acids due to its high dielectric constant. It has high compressive strength and a high melting point. It is also resistant to UV radiation darkening.
