產品系列說明

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、MgF₂、VIS 0°、NIR I及NIR 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-EXT, MgF₂, VIS 0^o, YAG-BBAR, NIR I, 還有 NIR II 抗反射膜選項
