TECHSPEC^®組件由愛特蒙特光學設計、指定或製造。進一步瞭解

YAG-BBAR 鍍膜平凹透鏡（PCV）

用於光束擴展或光投射應用的負焦距透鏡
在 532nm 和 1064nm 波長下優化 R<0.25%
具抗反射鍍膜，在 500-1100nm 範圍內每個表面可提供 <1.0% 的反射率
另有多種鍍膜選項：無鍍膜、 MgF₂、VIS 0°、 VIS-NIR、NIR I、NIR II 以及 1064nm V 型鍍膜

TECHSPEC® YAG-BBAR 鍍膜平凹（PCV）透鏡由平面和內曲面組成。這種透鏡的形狀因數產生了負的焦距。平凹透鏡（PCV）通常用於包括圖像縮小、光束擴展和望遠鏡在內的各種應用。TECHSPEC® YAG-BBAR 鍍膜平凹透鏡在常見的 Nd：YAG 雷射波長 532nm 和 1064nm 處的反射小於 0.25 %。這些透鏡另外也提供未鍍膜版本或是 VIS-EXT, MgF₂, VIS 0^o, VIS-NIR, NIR I, 還有 NIR II 抗反射膜選項
