    Product Parameter

    Silicon (Si) single crystal is a chemical inert material ,which is with high hardness and insoluble in water. It has good transmittance at 1 to 7μm wavelength. At the same time, it also has good transmittance in the far-infrared wavelengths 300-300μm, which unique compare with other infrared optical materials.Silicon (Si) is usually used in the 3 to 5μm middle wave infrared optical window and the optical filter substrate. The material has good thermal conductivity and Low density, which is also commonly used for making laser mirrors.
