尺寸多樣化
可選無鍍膜、 MgF2 鍍膜或 VIS-NIR 抗反射鍍膜
OEM批量採購可選擇客製尺寸

TECHSPEC® B270 窗鏡在可見光到近紅外（NIR）波段具有高穿透率，折射率與 N-BK7 相似，但成本效益更高。由於具有高日光照射穩定性和耐化學性，這些窗鏡通常用作保護元件，是標準窗鏡應用的理想選擇。TECHSPEC® B270 窗鏡系列提供無鍍膜版本，帶 MgF2 鍍膜或 VIS-NIR 抗反射鍍膜版本。可根據OEM應用需求對尺寸和鍍膜進行客製。TECHSPEC® B270 窗鏡在可見光到近紅外（NIR）波段具有高穿透率，折射率與 N-BK7 相似，但成本效益更高。由於具有高日光照射穩定性和耐化學性，這些窗鏡通常用作保護元件，是標準窗鏡應用的理想選擇。TECHSPEC® B270 窗鏡系列提供無鍍膜版本，帶 MgF2 鍍膜或 VIS-NIR 抗反射鍍膜版本。可根據OEM應用需求對尺寸和鍍膜進行客製。
