TECHSPEC^®組件由愛特蒙特光學設計、指定或製造。進一步瞭解

鍺 (Ge)平凸透鏡（PCX）

提供 3 - 5、3 – 12 以及 8 - 12µm 的鍍膜和無鍍膜選項
低色散具有低色差
適合於防禦、安全及熱成像等應用
另有其他常見基材的紅外透鏡可選
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) 平凸透鏡 (PCX) 採用精密金剛石車削基材，可提供無鍍膜或 3 - 12µm 的各種寬頻抗反射鍍膜選項。鍺(Ge)具有化學惰性、不溶於水、努氏硬度為 780，因此非常適合需要堅固光學元件的國防、安防以及熱成像應用。不過鍺會出現熱失控，因此應在低於 100°C 的溫度下使用，以確保最佳穿透效果。TECHSPEC® 鍺 (Ge) 平凸透鏡 (PCX)直徑為 12.5、25 和 50 mm。鍺的折射率很高（4.003），在沒有抗反射鍍膜的情況下會產生極大的菲涅耳反射損耗。TECHSPEC®鍺（Ge）平凸透鏡可提供無鍍膜或多種寬頻抗反射鍍膜（BBAR），以增強在中波紅外（MWIR）和長波紅外（LWIR）的穿透能力。

產品概覽

鍺因其高折射率、較大的穿透距離範圍和堅固的機械性能而廣泛應用。鍺的穿透範圍為 2 - 16 μm，且在可見光譜區是不透明的，因此十分適用於紅外雷射應用。但是，鍺會發生熱逸散現象，即隨著溫度的升高，穿透率會降低；事實上，鍺在 100°C 的溫度下幾乎是不透明的，在 200°C 的溫度下則完全沒有穿透性。當設計用於重量敏感系統的設備時，應考慮到鍺的高密度 (5.33 g/cm3) 特性。鍺的努氏硬度 (780) 約為氟化鎂的兩倍，這一特性使其成為有堅固光學元件要求的紅外線應用的理想之選。鍺不會與空氣、水、鹼金屬和酸（硝酸除外）發生反應。
