可調諧窄帶寬濾波器 (Laser Line Tunable filter)
LLTF是一種基於(yu) 全息體(ti) 布拉格光柵的非色散可調帶通濾波器。它提供了行業(ye) 中相對更高的信號吞吐量，而且它的獨特之處在於(yu) 它結合了高光密度(> OD6)和出色的帶外抑製與(yu) 超寬的可調範圍。單個(ge) 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)分別小於(yu) 2.5 nm和5 nm。定製和擴展光譜範圍(高達2500納米)和帶寬(亞(ya) 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，用戶能夠用一台LLTF實現對白光全波段（400 - 2500 nm）的濾波效果，可以很好地為(wei) 用戶減小空間成本。
