超寬帶可調(diào)諧激光器(tunable laser Source)
TLS系列超寬帶可調(diào)諧激光器是基于加拿大Photon
etc公司的可調(diào)諧濾波器技術及超連續(xù)譜光源技術研發(fā)而成的慢叨。調(diào)諧范圍從可見光到近紅外,激光線寬可達0.3nm务蝠。在整個調(diào)諧范圍內(nèi)可實現(xiàn)較高的準確性(precise
up to 0.05 nm)及準確度(accurate up to 0.1 nm)拍谐。
Photon etc 的光學線性可調(diào)濾波器(LLTF)是一種基于體積全息光柵的非色散可調(diào)帶通濾波器馏段。它提供了行業(yè)中相對較高的信號吞吐量轩拨,而且結(jié)合了高光密度(> OD6)和出色的帶外抑制以及廣泛的波段可調(diào)性。針對這點院喜,Photon將Fianium、NKT Photonics和LEUKOS Laser的超連續(xù)譜技術的靈活性與其本身的濾波器出色的帶外抑制特性相結(jié)合喷舀,推出了由超連續(xù)譜白光光源與LLTF搭建的TLS系列超寬帶可調(diào)諧激光器寸宵,允許應用于簡單而精確的樣品激勵或儀器校準。圖示為Photon的TLS輸出光譜圖元咙。
