超寬帶（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)諧技術(shù)及譜光源技術(shù)研發(fā)而成的。調(diào)諧范圍從可見光到近紅外，激光線寬最小可達(dá)0.3nm。在整個(gè)調(diào)諧范圍內(nèi)可實(shí)現(xiàn)*的準(zhǔn)確性（precise up to 0.05 nm)及準(zhǔn)確度（accurate up to 0.1 nm)。
的光學(xué)線性可調(diào)濾波器(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(duì)這點(diǎn)，Photon將Fianium、NKT Photonics和LEUKOS的超連續(xù)介質(zhì)技術(shù)的靈活性與其本身的濾波器的帶外抑制特性相結(jié)合，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，允許應(yīng)用于簡(jiǎn)單而精確的樣品激勵(lì)或儀器校準(zhǔn)。圖示為Photon的TLS輸出光譜圖。

注意：
輸入光束的散度要求不超過(guò)1 mrad，否則將無(wú)法有效工作。
如需在自由空間配置中達(dá)到此規(guī)格，需要將濾波器與Photon etc背景抑制附件耦合。
