ABSTRACT:
A spectrometer for determining the concentration of a substance within a sample comprises a. a radiation source (11) for supplying radiation to the sample to be measured; b. a filter (15) for filtering radiation transmitted by the sample, the filter having a number of pass bands at wavelengths corresponding to absorption peaks in the absorption spectrum of the sample to be detected, the filter being responsive to an applied signal to modulate the wavelengths of the pass bands; and, c. a detector (16) for detecting the filtered radiation, the detector being responsive to the applied signal to determine the relative intensities of the maxima and minima in the absorption spectra of the substance, characterized in that the radiation source is selectively activated in response to the applied signal.
