Near-IR spectroscopy belongs to the group of vibrational spectroscopy techniques, along with mid-infrared spectroscopy (primarily FT-IR) and Raman spectroscopy. The first near-IR spectrometers were ...
In the early 1940s, the first commercial dispersive spectrometers emerged for UV-Vis applications. This technology is based on the dispersion of light in dependence of its wave-lengths. The dispersion ...
