产品系列说明

用于光束扩展或光投射应用的负焦距
在 532nm 和 1064nm 波长下优化 R<0.25%
带有增透镀膜，在 500-1100nm 范围内每个表面可提供 <1.0% 的反射率
另有多种镀膜选项: 无镀膜, VIS-EXT, MgF₂, VIS 0°, VIS-NIR, NIR I, NIR II, and 1064nm V 镀膜

TECHSPEC® YAG-BBAR 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® YAG-BBAR 镀膜平凹透镜在常见的 Nd：YAG 激光波长 532nm 和 1064nm 处的反射小于 0.25 %。这些透镜还可提供无镀膜, VIS-EXT, MgF₂, VIS 0°, VIS-NIR, NIR I, 或带 NIR II 的增透镀膜（AR）选项。
