ABSTRACT:
A process for the manufacture of a glass capable of transmitting and reflecting radiant energy in an amount different from that transmitted and reflected by the original glass is disclosed. An ion implantation of appropriate materials into one or more layers of the glass produces a variation of density in the molecular structure of the layer and consequently a variation of the refractive index. The so obtained glass can be commercially used with no restrictions as to applications where there is contact with the external environment.
