     可調諧超窄帶濾波器  (Laser Line Tunable filter)

     

    LLTF是一種基于體積全息光柵的非色散可調帶通濾波器。它提供了行業中最高的信號吞吐量,而且它的獨特之處在于它結合了高光密度(> OD6)和出色的帶外抑制與超寬的可調范圍。單個濾波器可以在400 nm到1000 nm (VIS)或1000 nm到2300 nm (SWIR)之間進行調諧,帶寬(FWHM)分別小于2.5 nm和5 nm。定制和擴展光譜范圍(高達2500納米)和帶寬(亞納米)也可用。


    同時,Photon新推出的CONTRAST EXT-IV型號實現了更寬波段的覆蓋,用戶能夠用一臺LLTF實現對白光全波段(400 - 2500 nm)的濾波效果,可以很好地為用戶減小空間成本。
