產品系列說明

  • 繞射極限效能
  • 多種鍍膜選項
  • 提供完整產品說明資料
  • 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

TECHSPEC®鍺紅外線非球面透鏡能針對中波與長波紅外區域內的廣泛光譜範圍,提供繞射極限的聚焦效能。這些透鏡特別適用於單色光源 (例如量子串級雷射),可作為標準平凸透鏡的高效能替代方案。

每個非球面透鏡都提供無鍍膜或 BBAR 鍍膜選項。無鍍膜鍺的光線穿透率不足 50%,因此若指定使用無鍍膜透鏡,應考慮採用自訂抗反射 (AR) 鍍膜。每個 BBAR 鍍膜透鏡都能提供超過 95% 的穿透率,特別適合整合到多種 OEM 應用中。如需自訂設計或鍍膜選項,請聯絡我們的銷售部門
