Synthetic sapphire, often known as sapphire glass, is a popular window material because it is both very transparent to light wavelengths ranging from 150 nm (UV) to 5500 nm (IR) (the visible spectrum is from 380 nm to 750 nm) and extremely scratch-resistant.

The following are the primary advantages of sapphire windows:

Very broad optical transmission band (0.15-5.5 m) from UV to near-infrared.
Significantly stronger than standard glass windows or other optical materials
Highly scratch and abrasion resistant
Extremely high melting point (2030 °C)
