Silicon Lens
Silicon material has good thermal conductivity, low density, high hardness, and good light transmittance at 1.5-8um. Monocrystalline silicon is usually used as the substrate for 3-5μm mid-wave infrared optical windows, infrared lenses, and optical filters. It is also a common material for the reflector substrate in CO2 lasers and spectrophotometers
