  • 對於400 - 1000nm的光可為表面提供小於1.25%的反射率
  • 880nm光的反射率小於0.25%
  • 針對0°入射角而設計
  • 多種鍍膜選擇:無鍍膜MgF2VIS 0°NIR INIR II

TECHSPEC® VIS-NIR 鍍膜平凹透鏡 (PCV) 的設計目的是使平行輸入光線在鏡片輸出側彎折發散,從而使該鏡片具有負焦距。這些透鏡由於具有負球面像差,可用於平衡系統中其他透鏡所產生的像差。平凹透鏡(PCV)常用於包括影像縮小、擴束和望遠鏡等各種應用。 TECHSPEC® VIS-NIR 鍍膜平凹透鏡 (PCV) 針對近紅外線波長進行了透過優化(>99%)。這些透鏡另外也提供未鍍膜版本 或是 VIS-EXTMgF2VIS 0oYAG-BBARNIR I, 還有 NIR II 抗反射膜選項
