產品系列說明

採用抗反射鍍膜，可為 400 - 1000nm 的光提供每個表面小於 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, NIR II, VIS-EXT及YAG-BBAR

平凸（PCX）鏡片具有正焦距，是成像應用收光和聚光的理想選擇。它們也可用於多種其他包括發射器、偵測器、雷射和光纖的應用。帶有鍍膜的鏡片能提供最佳透光性。具有各種不同直徑和焦距可供選擇。

These coated lenses are optimized for a wide range of optics and photonics applications, including biotech instruments such as DNA sequencers and polymerase chain reaction (PCR) testing platforms.
