拉曼光纤探头
InPhotonics是RamanProbeTM拉曼光纤探头的，可提供高效的信号采集和激发激光线的*衰减。 同轴双光纤设计（美国5,122,127）使用微光学器件进行的光束控制，光学滤光和信号采集。 我们的探头都提供滤光功能，可将激光信号降低到远低于典型拉曼频带的强度。 这样获得清晰的光谱，避免瑞利“残余”进入低频区域以及探测器在不需要的激光线上饱和。 只有我们的拉曼探头才能在紧凑，灵活的探头中提供这种滤光，该探头已发展成为研究，分析和工业应用的完整产品线。
我们所有的探头都可用于六种不同的激发波长：514（Ar +），532（DPSS），633（He-Ne），670（二极管），785（二极管）和830（二极管）nm。 由于我们提供带有集成光纤的完整产品，我们的探头可提供50μm500μm的光纤尺寸，以匹配您的激光输出和光谱仪输入。 还提供其他功能，如成像和偏振检测。 我们的基本产品比较见附表。 可根据要求提供定制探头配置。 请咨询我们的专家，为您的仪器和应用找到适合的探头。
注意：用于FT-拉曼光谱的1064nm探头类似于拉曼探头和反应拉曼探头模型。 请查阅我们的1064 nm产品的各个规格表。
