An experimental study of the dispersion of the refractive indices n in (As2S3)x(AsI3)1-x glasses was performed. Experimental results were fitted by the Herzberger pentanomial which gave a possibility to calculate the dn/dλ and d2n/dλ2 values. In the short wave spectral domain the dispersion coefficient dn/dλ of the glassy As2S3 appears to be the same as in KRS-5, and with increasing the iodine concentration in the glasses the value of dn/dλ decreases. The zero-dispersion of the glasses under study is shifted towards the long waves as the iodine concentration increases.
