Paper Abstract

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/d(lambda) and d2n/d(lambda) 2 values. In the short wave spectral domain the dispersion coefficient dn/d(lambda) 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/d(lambda) decreases. The zero-dispersion os the glasses under study is shifted towards the long waves as the iodine concentration increases.
