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

The measurement spectral ranges of FT-IR spectrometers are defined by their major optical components which are the source, beamsplitter and detector. For modern research FT-IR spectrometers software controlled switching of the sources and detectors is available as standard functionality. The bottleneck was the need of an automated beamsplitter changer although that functionality was available for the first Bruker FT-IR spectrometer IFS112 already 40 years ago. The automatic beamsplitter exchange functionality was an essential design feature of the famous IFS113v based on a “Genzel” type interferometer.
