无镀膜平凹透镜 (PCV)

TECHSPEC Uncoated Plano-Concave (PCV) Lenses

波长范围是 400-2200nm
凭借精密的直径和向心性公差可轻松实现 OEM 集成
提供各种直径、焦距和镀膜
增透膜选择：MgF₂、VIS 0°、VIS-NIR、NIR I 和 NIR II

TECHSPEC® 无镀膜平凹透镜 (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® 无镀膜平凹透镜（PCV）可在 350nm 到 2200nm 范围内提供最佳性能。这些透镜还可提供 VIS-EXT, MgF₂, VIS 0°, VIS-NIR, YAG-BBAR, NIR I 或带 NIR II 的增透镀膜（AR）选项。
