VIS-NIR 带镀膜双凸透镜
- 产品详情
带AR镀膜，在400-1000nm范围内每个表面的反射率小于1.25% **限度地减少球差和慧差 提供紫外熔融石英双凸透镜 其他镀膜选项： 未镀膜、 MgF2、NIR I、 NIR II、 VIS-EXT、 VIS-NIR 和 YAG-BBAR 通用规格 倒角 Protective bevel as needed 涂层 VIS-NIR (400-1000nm) 涂层规格 Rabs ≤0.25% @ 880nm Ravg ≤1.25% @ 400 - 870 nm Ravg ≤1.25% @ 890 - 1000nm 焦距容差 (%) ±1 波长范围 (nm) 400 - 1000 TECHSPEC® VIS-NIR镀膜双凸透镜有两个正的、对称的面，两边的半径相等。这些透镜通常被推荐用于共轭比（物距和像距之间的比率）在0.2和5之间的有限成像应用。在共轭比为1时，由于对称透镜的设计，球差、色差、慧差和畸变等像差得以最小化或消除。TECHSPEC 双凸透镜有多种基底和镀膜可选，适用于可见光和近红外光谱。 N-BK7 Typical transmission of a 3mm thick, uncoated N-BK7 window across the UV - NIR spectra.
