Silicon is a semiconductor material commonly used in infrared optical systems operating in the near-IR and MW spectral band. Silicon has the lowest density among common infrared materials, making it ideal for systems with weight constraint.
Silicon is used as an optical window primarily in the 3 to 5 micron band and as a substrate for production of optical filters.
Note for Silicon windows:
1.Custom-made Silicon windows at any size from 2.0mm to 100mm clear aperture are available. besides round, Silicon windows at shape of quadrate ,triangular or other polygonal are available
2. Thickness from 0.5mm to 10.0 mm is available upon request.
3. Better bevel is available upon request.
