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。

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。
