WebOct 9, 2024 · How does Fourier Transform Infrared Spectroscopy (FTIR) work? Light from an FTIR light source is split into two beams by a beam splitter (similar to a half mirror). One beam is transmitted to the moving mirror and the other beam is reflected by the fixed mirror. The goal of absorption spectroscopy techniques (FTIR, ultraviolet-visible ("UV-vis") spectroscopy, etc.) is to measure how much light a sample absorbs at each wavelength. The most straightforward way to do this, the "dispersive spectroscopy" technique, is to shine a monochromatic light beam at a sample, measure how much of the light is absorbed, and repeat for each different wave… opal warehouse
