Why Sapphire?
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.
Sapphire Windows are manufactured from single crystal sapphire, making them ideal
for demanding applications (such as laser systems) because of their extreme surface hardness, high
thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis.
Sapphire is the second hardest crystal next to diamonds, because of their structural strength,sapphire
windows can be made much thinner than other common dielectric windows with improved
transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3) and is useful in a
transmission range from 0.2 - 5.5μm.
