UV and Visible Spectrometers Information UV and visible spectrometers measure the amount of ultraviolet and visible light transmitted or absorbed by a sample placed in the spectrometer. The wavelength at which a chemical absorbs light is a function of its electronic structure and the intensity of the light absorption is related to the amount of the chemical between the light source and the detector, so a UV / Visible spectrum can be used to identify some chemical species. Photometric...
