1. Why choose the sapphire?

Thinner and Stronger than Standard Glass Windows
Transmits Wavelengths Ranging From UV to Mid-Infrared
Features Extreme Surface Hardness and Chemical Resistance
 

2,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.
