摘要: The description relates to optical glasses with a refractive index varying as a function of at least one co-ordinate, produced using a basic material with a constant refractive index by ion exchange. Greater index gradients than those obtainable in the present state of the art are obtained by means of special compositions and appropriate ion exchange baths. In addition, the stability of the glasses is increased.
