标题: 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。
