Abstract

PURPOSE:To provide a method for cheap and economical production of preforms satisfying characteristics required in light transmission such as low transmission loss or small transmission deflection by removing foams from porous glasses in which refractive indices are changed in stages in the direction of radius, followed by melt spinning.
