    • A multifunctional infrared spectrometer system has an interferometer which receives the infrared beam from a source and provides a modulated output beam on beam paths to multiple spatially separated infrared detectors. A multi-position mirror element mounted at a junction position receives the beam on a main beam path and directs it on branch beam paths to sample positions, with the beam then being directed on the branch beam path to one of the detectors. One of the branch beam paths may include a sample holder at the sample position which can index between a position at which a sample is analyzed, to a reference material position, to a pass-through position for calibration purposes. The multi-position mirror element may also be indexed to direct the beam on a branch path to a fiber optic cable which has a probe at the end of it which may be inserted in a sample fluid or powder to be analyzed, with the reflected light from the probe being directed back on an optical fiber cable to a detector at the spectrometer. The multi-position mirror element may be moved to a position at which the beam is directed on a beam path to and through an integrating sphere to a solid sample, with the reflected light from the sample being directed by the surfaces of the integrating sphere to a detector. A detector may be mounted to detect the light transmitted through the sample to obtain measurements of both reflected and transmitted infrared light at the sample.
    • 多功能红外光谱仪系统具有干涉仪,其接收来自源的红外光束,并将光束路径上的调制输出光束提供给多个空间分离的红外探测器。 安装在连接位置处的多位镜子元件在主光束路径上接收光束并将其引导到分支光束路径到采样位置,然后光束被引导到分支光束路径到其中一个检测器。 分支光束路径中的一个可以包括在采样位置处的样品保持器,其可以将样品被分析的位置与参考材料位置之间的位置转换成用于校准目的的通过位置。 多位置反射镜元件还可被索引以将光束引导到光纤电缆的分支路径上,该光纤电缆在其末端具有探针,该探针可以插入待分析的样品流体或粉末中,其中反射光 从探头引导回光纤光缆到光谱仪上的检测器。 多位置反射镜元件可以被移动到光束被引导到通过积分球并通过积分球的光束到固体样品的位置,其中来自样品的反射光被积分球的表面引导到 检测器 可以安装检测器以检测通过样品透射的光,以获得样品上的反射和透射的红外光的测量。
