Fourier-transform infrared spectroscopy - Wikipedia

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… WebAug 16, 2024 · An FTIR instrument uses an interferometer (Figure 4), which consists of a source, beam splitter, two mirrors, a laser and a detector.
