ABSTRACT:
In an analysis system including as light sources an incandescent lamp and a blue light emitting diode, the light of the two sources is combined and directed through filters and a test tube with material to be examined to a photodiode array spectrometer. The filters are so selected that they counteract the intensity drop of the incandescent lamp and the sensitivity decrease of the photodiode array of the spectrometer at short wave lengths.
