Cadmium tungstate single crystals doped with Cr3+ are grown by Czochralskrtechnique. The absorption spectra are measured. The low peaks of Cr3+ are due to the selfabsorption induced by the colour centers and the impurities. The positions of the major energylevels 4T1, 4T2 and 2E of Cr3+ and the energy level difference E=-1430cm-1 between 2E and4T2 are determined.
