Monocrystal Silicon ( Si ) in the 1.2-7um band has good transmation, and it in the Far Infrared band 30-300 micron also has good transmation too, which is not the characteristics of other infrared materials. It is usually used as the substrate of 3-5um medium infrared optical windows.
Monocrystalline silicon optical windows can be used in adjacent fields such as gas detection and infrared sensors. Creator Optics can customize silica windows in a variety of shapes. The shape is the same as the ordinary optical window of other materials. In additional, we can customize a variety of infrared coatings for these silicon windows.
