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.

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.
