The extension of the mid IR towards the far IR spectral range below 400 cm-1 is of general interest for molecular vibrational analysis for various application fields and industry branches. Till now, to extend the spectral range, one or more additional far IR beamsplitters and detectors are required and the user has to manually open the spectrometer optics bench.

The unique Bruker FM technology for VERTEX 70v and INVENIO R FT-IR research spectrometers which combines the wide spectral range beamsplitter, the wide range DTGS detector and the standard IR source to cover the spectral range from 6000 cm^-1 down to 50 cm^-1 (for INVENIO R from 6000 cm^-1 down to 80 cm^-1) in one single scan for all types of transmittance, reflectance and ATR measurements.

Main Application Fields of Bruker FM

• Inorganic and organometallic chemistry

• Semiconductor development and research

• Studies on polymer filler material and color pigments

• Geological and rock analysis (mining)

• Pharmaceutical fillers and active agent measurements

• Polymorphs differentiation

• Crystallinity identification

• Product and material comparison

• Low temperature matrix isolation spectroscopy
