Zusammenfassung:A method and apparatus for a densitometer comprising a multicolor LED having a light adjustment mechanism for controlling the amount of light received by a light detector in the densitometer. The MCLED is comprised of a plurality of different color LEDs and a controller selects the current to each LED by wavelength to maximize the absorption by the colorant yielding light roughly complimentary to the colorant.
