產品系列說明

  • 適用穿透範圍 600nm至16μm
  • 低色散

硒化鋅是化學蒸著材料,通常用於熱成像、FLIR與醫療系統。由於對熱衝擊的吸收係數低、抵抗能力強,因此廣泛用於高功率CO2雷射系統。硒化鋅材料相對較軟 (努氏硬度 120),易產生刮痕,建議不要在粗糙的環境中使用。在搬動、安裝及清潔期間,必須格外小心。在搬動時請均勻用力,請戴上乳膠指套或手套防止弄髒,請勿使用鑷子或其他工具。

Note: Special care should be taken when handling Zinc Selenide as it is a toxic material. Always wear rubber or plastic gloves to avoid risk of contamination.
