产品系列说明

带有增透镀膜，在 750-1550nm 范围内每个表面可提供 <0.7% 的反射率
专为 0° 入射角设计
另有多种镀膜选项: 无镀膜, VIS-EXT, MgF₂, VIS 0°, VIS-NIR, YAG-BBAR, 和 NIR I

TECHSPEC® NIR II NIR II 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® NIR II 镀膜平凹透镜（PCV）可在 750nm 到 1550nm 范围内提供最佳性能。这些镜片还可提供无镀膜、 VIS-EXT、 MgF₂, VIS 0°, VIS-NIR, YAG-BBAR, 或 NIR I 增透镀膜选项。
