TECHSPEC® Silicon (Si) Windows

Silicon (Si) Windows
  • Transmission from 1.2 - 7µm
  • Available Uncoated or AR Coated for 3 - 5µm
  • Ideal for Weight Sensitive Applications

TECHSPEC® Silicon (Si) Windows manufactured from optical grade silicon are popular for the 1.2 - 7µm spectral region due to their low cost and low density. Due to its low density (half that of germanium or zinc selenide), silicon is ideal for weight sensitive applications, especially those in the 3 - 5µm region. Density is 2.329 g/cm3 and Knoop Hardness is 1150, making it harder and less brittle than germanium.
