產品概覽

  • 提供未鍍膜或鍍抗反射鍍膜選項,適用於各種红外應用
  • 低色散帶來最小的色像差
  • 非常適用於需要堅固光學裝置的紅外應用
  • 也供應 DLC 鍍膜鍺窗鏡
  • 由於鍺的材料供應鏈中斷,我們的鍺產品的交貨時間可能會增加,價格也會有所變動。欲了解更多訊息,請聯繫我們的客戶服務團隊
  • Edmund Optics 的該零件號剩餘庫存有限,一旦耗盡,由於沒有原材料,將無法供應。 請聯絡我們的產品支援工程師,協助您找到滿足您需求的替代解決方案。客戶服務部門可為您提供最新的價格和供應情況"。

TECHSPEC®鍺(Ge) 窗鏡現貨供應,可選三種抗反射鍍膜: 3 - 5μm波段適用於中紅外應用,3 - 12μm波段適用於寬帶多光譜應用, 8 - 12μm波段適用於熱成像應用。由於鍺窗口片的折射率很高 (對於2 - 14μm的光大約為4.0),因此建議在這些鍺窗口片上使用抗反射鍍膜,以便在所需範圍內實現充足的穿透。鍺受温度影響嚴重,穿透率隨温度的升高而降低,因此,只能適用於100°C以下溫度的應用。在設計對重量有嚴格要求的系统時要考慮鍺的高密度(5.33 g/cm3)。鍺的努氏硬度是780,大約是氟化鎂硬度的兩倍,非常適用於需要堅固光學特性的紅外應用。
