产品系列说明

在400 - 1000nm波段每个镀膜面的反射率<1.25%
在880nm每个面的反射率小于0.25%
设计入射角为0度
多种镀膜选择：无镀膜, VIS-EXT, MgF₂, VIS 0°, YAG-BBAR, NIR I 和 NIR II

TECHSPEC® VIS-NIR 镀膜平凹透镜 (PCV) 的设计目的是使平行输入光线在镜片输出侧弯折发散，从而使该镜片具有负焦距。这些透镜由于具有负球面像差，可用于平衡系统中其他透镜产生的像差。平凹透镜（PCV）常用于包括图像缩小、扩束和望远镜等各种应用。TECHSPEC® VIS-NIR 镀膜平凹透镜 (PCV) 针对近红外波长进行了透过优化（>99%）。这些透镜还可提供无镀膜, VIS-EXT, MgF₂, VIS 0°, YAG-BBAR, NIR I, 或带 NIR II 的增透镀膜（AR）选项。
