產品系列說明

  • 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MgF2VIS 0°VIS-NIRNIR INIR 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-EXTMgF2, VIS 0o, VIS-NIRNIR I, 還有 NIR II 抗反射膜選項
