产品描述
硒化锌 (ZnSe) 平凸 (PCX) 透镜
由爱特蒙特光学设计，II-VI 材料制成
优质等级的硒化锌材料
无镀膜或宽带抗反射镀膜选项
TECHSPEC® 硒化锌 (ZnSe) 平凸 (PCX) 透镜的设计用于中波和长波红外光谱中的聚焦或准直应用。这些透镜由 II-VI 红外硒化锌材料制成，在 10.6µm 波长上的体积吸收系数为 <0.0005cm-1，可提供无镀膜或多种宽带抗反射镀膜选项。8-12µm 镀膜非常适合与 CO2 激光器和热感照相机应用搭配使用，而双波段的 3-12µm 镀膜则适用于高光谱应用。TECHSPEC® 硒化锌平凸透镜在 10.6µm 波长上的不规则性为 <λ/20 ，表面质量为 40-20，表面粗糙度 <50Å。提供三种直径选项，有效焦距范围从 12.7mm 到 200mm。
