- 產(chǎn)品型號：
- 更新時間：2023-12-19
- 產(chǎn)品介紹：拉曼光纖探頭可提供高效的信號采集和激發(fā)激光線的*衰減。 同軸雙光纖設(shè)計（美國5,122,127）使用微光學(xué)器件進(jìn)行的光束控制，光學(xué)濾光和信號采集。 我們的探頭都提供濾光功能，可將激光信號降低到遠(yuǎn)低于典型拉曼頻帶的強度。 這樣獲得清晰的光譜，避免瑞利“殘余"進(jìn)入低頻區(qū)域以及探測器在不需要的激光線上飽和。

拉曼光纖探頭
InPhotonics是RamanProbeTM拉曼光纖探頭的，可提供高效的信號采集和激發(fā)激光線的*衰減。 同軸雙光纖設(shè)計（美國5,122,127）使用微光學(xué)器件進(jìn)行的光束控制，光學(xué)濾光和信號采集。 我們的探頭都提供濾光功能，可將激光信號降低到遠(yuǎn)低于典型拉曼頻帶的強度。 這樣獲得清晰的光譜，避免瑞利“殘余”進(jìn)入低頻區(qū)域以及探測器在不需要的激光線上飽和。 只有我們的拉曼探頭才能在緊湊，靈活的探頭中提供這種濾光，該探頭已發(fā)展成為研究，分析和工業(yè)應(yīng)用的完整產(chǎn)品線。
我們所有的探頭都可用于六種不同的激發(fā)波長：514（Ar +），532（DPSS），633（He-Ne），670（二極管），785（二極管）和830（二極管）nm。 由于我們提供帶有集成光纖的完整產(chǎn)品，我們的探頭可提供50μm500μm的光纖尺寸，以匹配您的激光輸出和光譜儀輸入。 還提供其他功能，如成像和偏振檢測。 我們的基本產(chǎn)品比較見附表。 可根據(jù)要求提供定制探頭配置。 請咨詢我們的專家，為您的儀器和應(yīng)用找到適合的探頭。
注意：用于FT-拉曼光譜的1064nm探頭類似于拉曼探頭和反應(yīng)拉曼探頭模型。 請查閱我們的1064 nm產(chǎn)品的各個規(guī)格表。
