Application Note: BRUKER FM: Far and Mid IR Spectral Range Spectroscopy in One Step
23 November 2018

The measurement spectral ranges of FTIR spectrometers are defined by their major optical components which are the source, beamsplitter and detector. For modern research FTIR spectrometers software controlled switching of the sources and detectors is available as standard functionality. The bottleneck was the need of an automated beamsplitter changer. Due to the high development costs and technological demand for an automatic beamsplitter changer it was not available for FTIR spectrometers for a long period of time. In 2010 Bruker introduced a 4 position automatic beamsplitter changer BMS-c which works under vacuum condition for its high-end research bench-top FTIR spectrometer VERTEX 80v providing unmatched performance.
