Silicon (Si) is one of the hardest minerals and optical materials available for use in the NIR (1µm) to about 6µm. Optical quality Silicon is usually doped (5 to 40 ohm cm) to prevent absorption bands within the transmission waveband. Silicon has a lower refractive index than germanium and has a lower density that makes for less weighty optical designs.

Silicon is ideal for use as windows in the 3 to 5µm (MWIR) waveband and as substrate for optical filters. This waveband (3 to 5µm) is important for the detection of sources radiating at a black body temperature of 700K, such as the muzzle flash from guns, such as sniper rifles and mortar pieces. Every component is individually tested by our highly skilled technicians in our state of the art metrology lab to ensure all components meet our high quality standards. Its transmission is about 50% within the 1 to 6µm and above 50µm, which will mean that anti-reflection coatings are required to improve the transmission ...
