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。
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。
