Abstract

Manufacturing problems concerning glasses used for making of GRIN type lenses have been presented. The most important requirements to glass quality is its high chemical and physical homogeneity. The results in obtaining of GRIN structure made of glasses melted on a laboratory scale in electrical resistance furnace as well in induction furnace have been presented. The quality of the glasses obtained has been compared with the glass melted in Optical Glass Works in Jelenia Gora. It has been determined the direction of the glass homogeneity optimization by the use of the single-step method of glass rods manufacturing by pulling them from the induction heated crucible.
