Paper Abstract

Silver aluminum phosphate glassed have been tested as a material for gradient index (GRIN) elements fabrication by exchange of Na+ ions from mixed molten salt baths by the Ag+ ones. The annealing technique was used to control the final gradient and GRIN rod elements with radial index profile were prepared with n(r) equals no(1 - A/2 (DOT) rn) where 2 1/2 is congruent to 0.075. The calculated longitudinal aberration was smaller then 5 micrometers within the region of 50% radius from axis.
