What is sapphire?
Synthetic Sapphire is a single crystal form of corundum, Al2O3, also known as alpha-alumina, and single crystal Al2O3,have 9.0 hardness.
Sapphire is aluminium oxide in the purest form with no porosity or
grain boundaries, making it theoretically dense.
The combination of favourable chemical, electrical, mechanical,optical, surface, thermal, and durability properties make sapphire
a preferred material for high performance system and component
designs. For various semiconductor applications,
sapphire is the best choice in comparison with other synthetic
single-crystals.

Features
Extremely high surface hardness
◆ High temperature resistance
◆ Good thermal performance
◆ Excellent electrical and dielectric properties and chemical
resistance
◆ Emission range from ultraviolet to mid-infrared
The luminescence source of the 308 nm excimer phototherapy system
is a molecule composed of a cesium atom (Xe) and a chlorine atom
(Cl) under the action of a high frequency electric field. The
chlorine atom accepts an electron from a helium atom. When
activated, the two atoms are in an unstable state of binding
(excimer), resulting in a single-frequency excimer light.
Features:
The excimer light wavelength is single, the energy distribution is
uniform, the depth of the skin is controllable, and the cross
section is flat.
How about advantage of sapphire glass?
1- Thinner and Stronger than Standard Glass Windows
2- Transmits Wavelengths Ranging From UV to Mid-Infrared
3- Features Extreme Surface Hardness and Chemical Resistance
