About Sapphire
Single crystal sapphire possesses a unique combination of excellent optical, physicaland chemical properties. The hardest of the oxide crystals, sapphire retains its high strength at high temperatures,
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
