This optical device, first introduced by Bausch & Lomb in 1953, is typically used to determine the level of a component dissolved in a solvent. Visible light from a lamp is separated into its spectrum, or colors, by a prism. A specific color or wavelength light, specified by the user, is directed through a small vial of the liquid into a detector. If the component can absorb the light at this wavelength, less light hits the detector. Such a reduction in transmitted light intensity corresponds to the concentration of the absorbing component.
