IR Spectrometers - Thermo Fisher Scientific
Spectrometers that measure the interaction of infrared radiation with matter by absorption, emission, or reflection, using IR spectra to identify chemical substances or functional groups in solids, liquids, or gasses. Includes instruments and accessories.
Infrared spectroscopy - Wikipedia
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms.

An FTIR spectrometer uses a Michelson interferometer to separate a collimated beam of polychromatic infrared light into two different optical paths that results in constructive and destructive interference based on the relative positions of a stationary and moving mirror.
Guide to FT-IR Spectroscopy - Bruker
Infrared, or IR, spectroscopy is a chemical analysis technique that takes advantage of the interaction between infrared light and matter. Infrared light is part of the electromagnetic spectrum between visible light and microwaves, with wavelengths ranging from 780 nm to 1 mm.
