Uncoated Sapphire windows are ideal for harsh conditions, including environments subject to high temperatures, high pressures, strong vacuum, or corrosive atmospheres. Sapphire has high compressive strength and is resistant to attack from strong acid.

• Ideal for high temperature, high pressure, or strong vacuum environments

• Highly corrosion resistant

• Transparent from 170 nm to 5.5 μm

• Extremely hard and more durable than standard optical glass

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.
