產品系列說明

愛特蒙特光學設計，II-VI製造
高級硒化鋅材料
無鍍膜或寬頻抗反射鍍膜選項

TECHSPEC®硒化鋅(ZnSe)平凸(PCX)透鏡專為中波和長波紅外光譜中的聚焦或準直應用而設計。這些透鏡由II-VI製造，採用10.6µm時具有<0.0005cm^-1的體吸收的紅外硒化鋅材料，並提供無鍍膜或各種寬頻防反射鍍膜選項。8-12µm塗層非常適用於CO₂雷射和熱感攝影機應用，而雙頻3-12µm鍍膜是高光譜應用的理想選擇。TECHSPEC®硒化鋅PCX透鏡具有<λ/20的不規則度（在10.6µm時）、40-20表面品質及<50Å表面粗糙度。提供三種直徑選項，有效焦距範圍為12.7mm至200mm。
