Features

Handles High Temperatures and Pressures

Sapphire windows are highly tolerant of extreme temperature and pressure differences. These windows are commonly used as viewports enable viewing inside of vacuum chambers, or chambers containing high temperature plasma.

Wide Transmittance Range

Uncoated Sapphire is transparent across a wide wavelength range from 170 nm to 5.5 µm.

Unique Sapphire Material Properties

Sapphire is a single crystal form of Al2O3, with a favorable combination of chemical, mechanical and optical properties. Sapphire is resistant to attack by strong acids, enabling use in a corrosive atmosphere. It is resistant to scratch and abrasion with very high Knoop hardness of 1800 parallel to the optic axis (C-axis), 2200 perpendicular to the optic axis.

Note on Birefringence

The SAW series sapphire windows are provided with a random axis orientation. As sapphire is slightly birefringent, this may result in slight alteration of the polarization state of transmitted light.
