Abstract

This paper discusses the results of laboratory studies and commercial melts of multicomponent germanate glass containing sodium oxide. Ion exchange of commercial glass plates in a eutectic mixture of lithium chloride and sulfate was used to obtain flat scattering gradient-index elements with a parabolic refractive-index distribution. The distribution formula is derived. Concepts are formulated concerning the mechanism by which the refractive-index profile is formed.
