【簡(jiǎn)單介紹】
【詳細(xì)說明】
可調(diào)諧超窄帶 (Laser Line Tunable )
LLTF是一種基于體積全息的非可調(diào)帶通濾波器。它提供了行業(yè)中的信號(hào)吞吐量，而且它的之處在于它結(jié)合了高光密度(> OD6)和出色的帶外抑制與超寬的可調(diào)范圍。單個(gè)濾波器可以在400 nm到1000 nm (VIS)或1000 nm到2300 nm (SWIR)之間進(jìn)行調(diào)諧，帶寬(FWHM)分別小于2.5 nm和5 nm。定制和擴(kuò)展光譜范圍(高達(dá)2500納米)和帶寬(亞納米)也可用。
同時(shí)，Photon新推出的CONTRAST EXT-IV型號(hào)實(shí)現(xiàn)了更寬波段的覆蓋，用戶能夠用一臺(tái)LLTF實(shí)現(xiàn)對(duì)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。
PHOTON ETC的光學(xué)濾波技術(shù)使得LLTF提供了的效率和帶外抑制，是熒光和中可調(diào)諧激發(fā)源的理想選擇。
