Optical Tunable Filter (可调谐超窄带滤波器)

产品名称：Optical Tunable Filter (可调谐超窄带滤波器)
所属类别：Tunable Filter（可调谐光学滤波器）
厂家名称：昊量光电
产品简介： LLTF系列Laser Line Tunable Filter是一款非色散的亚纳米带宽可调谐光学滤波器。值得一提的是，因为采用的拥有专利的体光栅技术，这款可调谐光学滤波器具有惊人的60%的非偏振透过率，这是FTS, Fabry-Perot, 声光（AOTF），液晶（LCTF）等方法所无法企及的。波长调谐通过电脑程序控制，省去了重新调整光路带来的不便。此外，由于TNF系列超窄带宽Notch Filter中的filter是由全玻璃材料制成，所以和传统的Notch Filter比较，它具有更高的损伤阈值及工作寿命。
