has good thermal properties and excellent transparency. It is
chemically resistant to common acids and alkali at temperatures up
to 1000 °C as well as to HF below 300 °C . These properties
encourage its wide use in hostile environments where optical
transmission in the range from the vacuum ultraviolet to the near
infrared is required. Sapphire is anisotropic hexagonal crystal.
Its properties depend on crystallographic direction (relative to
the optical C-axis).
So what superiority sapphire have??
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
