Sapphire crystals have the following exceptional properties that make it a very important optics single crystal:

(1) High optical transmittance from the vacuum ultraviolet to the infrared spectrum region(0.2-5.5um). And shows excellent transmittance in the UV regions.

(2) Used for Optical prisms, lenses, wedges, windows, other optical components, and etc.

Main properties:
Melting point: 2050 degree
Density: 3.98G/CM3
Moths: 9
Young's Modulus: 53 Mpsi
Transmission Band: 200nm-5.5um

Applications:
Window sheet

Sapphire is a kind of single crystal alumina with high heat-resistant, high melting point, high strength, high transparency, high hardness and resistance to chemical attack. It can be used not only as infrared and ultraviolet transmitting windows of aerospace instrument, laser, blast furnace temperature measuring, but also as solar cell protective shield and cover of watch. Sapphire is used as window sheet that has advantages as follows:

Transparency band from 200-5500nm
Transmission ratio of infrared at 3000-5000nm > 85%
High hardness, high transparency, transverse strength, resistance to chemical attack
Good thermal conductivity coefficient
