產品系列說明

  • 採用抗反射鍍膜,對於750 - 1550nm的光可為表面提供小於0.7%的反射率
  • 針對0°入射角而設計
  • 多種鍍膜選擇:無鍍膜MgF2VIS 0°VIS-NIRNIR I

TECHSPEC® NIR II 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® NIR II 鍍膜平凹透鏡(PCV)可在 750nm 到 1550nm 範圍內提供最佳性能。這些透鏡另外也提供未鍍膜版本 或是 VIS-EXTMgF2, VIS 0oVIS-NIRYAG-BBAR, 還有 NIR I 抗反射膜選項。
