Synthetic sapphire—sometimes referred to as sapphire glass—is
commonly used as a window material, because it is both highly
transparent to wavelengths of light between 150 nm (UV) and 5500 nm
(IR) (the visible spectrum extends about 380 nm to 750 nm, and
extraordinarily scratch-resistant.
The key benefits of sapphire windows are:
Very wide optical transmission band from UV to near-infrared,
(0.15–5.5 µm)
Significantly stronger than other optical materials or standard
glass windows
Highly resistant to scratching and abrasion
Extremely high melting temperature (2030 °C)
