  • 穿透範圍為 1.2 - 7μm
  • 可提供無鍍膜或適用3 - 5μm範圍內的 HDAR 鍍膜
  • 適用於對重量敏感的應用

ISP Optics 矽窗鏡提供 1.2 - 7μm 範圍的近紅外(NIR)和中波紅外(MWIR)穿透。矽的努氏硬度為1150,相比鍺,矽更硬,鍺更脆。高耐久性抗反射(HDAR)鍍膜選項增加了基材的耐久性,同時顯著提高了在3 - 5μm範圍內的穿透率,能夠在惡劣的環境中使用。ISP Optics 矽窗鏡是對重量敏感的紅外應用的理想選擇,密度低至2.329 g/cm3,是鍺和硒化鋅的一半。這些窗鏡是近紅外成像應用的理想選擇,對於檢測溫度為700K的輻射黑體來源非常重要。
