SILICON (Si) OPTICS
Silicon is used as a high reflectivity mirror for lasers. It is used for windows and lenses in the 1mkm to 7mkm range. The refractive index is near 3.4 throughout the range. Its high thermal conductivity and low weight are attractive features in some applications. Due to the strong absorbtion at 9mkm, Silicon is not suitable for use with CO2 lasers as a transmitting optic but is widely used for CO2 mirrors. The density of Silicon is only half that of Germanium and Zinc Selenide. Alkor Technologies manufactures Silicon optical components according to customer's specification: Si windows, Si lenses, Si prisms, Si mirrors made in monocrystalline, polycrystalline and floatzone material. The largest dimensions of Si optics: Dia 150x20mm. Please contact us for more information. Main properties:
Chemical Formula : Si Crystal Structure : Diamond Cubic Lattice Constant, A : 5.43 Density, g/cm3 : 2.329 Mohs Hardness :7 Transmission band: 1.2 - 10 mkm Refractive Index
