產品系列說明

  • 低色散
  • 無鍍膜或提供抗反射鍍膜
  • 非常適用於熱成像、FLIR與醫療系統

TECHSPEC®硒化鋅 (ZnSe) 窗鏡非常適用於多種紅外應用 (包括熱成像、FLIR與醫療系統)。此化學蒸著材料對熱衝擊的吸收係數低、抵抗能力強,因此廣泛用於CO2雷射系統。硒化鋅 (ZnSe) 材料相對較軟 (努氏硬度只有120),易產生劃痕,建議不要在粗糙的環境中使用。在處理時請均勻用力,請戴上乳膠指套或手套防止弄髒。

注意: 在拿取硒化鋅時需要特別小心,因為其為有毒物質。在操作過程的全程都需要戴上橡膠手套或塑膠手套以避免接觸。

技術資訊

AR COATED ZINC SELENIDE

Typical visible transmission of a 3mm thick ZnSe window coated with BBAR (1650-3000nm), BBAR (3000-12000nm), and BBAR (8000-12000nm coating).

This data is outside the design wavelength range of the BBAR coatings and thus is not guarenteed, but provides a reference for visible guide laser useage.
