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 seed crystal is slowly pulled upwards and may be rotated simultaneously. By precisely controlling the temperature gradients, rate of pulling, and rate of temperature decrease, it is possible to produce a large, single-crystal, roughly cylindrical ingot from the melt.
After single crystal sapphire boules are grown, they are core-drilled into cylindrical rods, The rods are sliced up into the desired window thickness and finally polished to the desired surface finish.

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)
