    Description

    Si Windows

    Silicon window is suitable for the near-infrared band in the 1.2-8μm region. Because silicon material has the characteristics of low density (its density is half that of germanium material or zinc selenide material), it is especially suitable for some occasions that are sensitive to weight requirements, especially for applications in the 3-5μm band. The Knoop hardness of silicon is 1150, which is harder than germanium and is not brittle as germanium. However, due to its strong absorption band at 9um, it is not suitable for transmission applications of carbon dioxide lasers.


    Material: Si
    Dimension Tolerance: 0.0/-0.1mm
    Thickness Tolerance: ±0.2mm
    Clear Aperture: ≥90%
    Surface Quality: 40/20
    Flatness: λ/4@633nm
    Parallelism: ≤3′
    Chamfer: 0.3×45°
    AR Coating: Ravg<3% per surface@3-5μm
    Other coating is customized.
