A schlieren system of the z type has been designed and used to characterize the chromatic variation of index of refraction gradients. Samples of gradient-index glass produced by Bausch & Lomb (Rochester, New York), Schott Optical (Mainz, West Germany), and University of Rochester (Rochester, New York) have been characterized.
