Product Description

Product Description
Optical windows are falt, plane parallel plates which are often used as protective barriers for electronic sensors or detectors from outside environments. When selecting windows, please consider materials, transmission, scattering, parallelism and resisitance to certain environment or mechanical properties of the substrate.

Silicon (Si) Windows
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.
