TECHSPEC®硒化锌(ZnSe)窗口片是广泛红外应用的理想选择,包括用于热成像、FLIR及医疗系统。它的吸收系数低,并对热冲击具有高度的抵抗性,因此这种气相沉积材料在二氧化碳激光系统中受到广泛的使用。硒化锌(ZnSe)是一种较易刮花的软性材料,因此不适合在恶劣的环境中使用(努氏硬度仅为120)。处理时,必须施以一致的压力,并且戴上乳胶指套或手套来防止污染。
注意: 在拿取硒化锌时需要特别小心,因为其为有毒物质。在操作过程的全程都需要佩戴橡胶手套或塑料手套以避免接触。

Typical transmission of a 3mm thick ZnSe window with BBAR (1650-3000nm) coating at 0° AOI. The blue shaded region indicates the coating design wavelengh range, with the following specification: Ravg <1% @ 1650 - 3000nm Data outside this range is not guaranteed and is for reference only. |
Typical transmission of a 3mm thick ZnSe window with BBAR (3000-12000nm) coating at 0° AOI. The blue shaded region indicates the coating design wavelengh range, with the following specification: Ravg <5.0% @ 3 - 12μm Data outside this range is not guaranteed and is for reference only. |
