1. Sapphire glass are manufactured from Al2O3 single crystal, ideal material for  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 and, 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.
