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
