Silicon (Si) Windows

• Transmission from 1.2 - 7pm

Available Uncoated or AR Coated for 3 - 5pm

Ideal for Weight Sensitive Applications

Silicon (Si) Windows manufactured from optical grade silicon are popular for the 1.2

- 7pm spectral region due to their low cost and low density. Silicon is ideal for

weight sensitive applications, especially those in the 3 - 5pm region. Density is 2.329

g/cm3 and Knoop Hardness is 1150, making it harder and less brittle than

germanium.
