ABSTRACT:
Glass compatible metal matrices are mounted in a glass forming boat and slugs of glass are applied to each. Heat is provided such that openings in the matrix are glassed, whereupon the entire sheet may be ground, polished, or otherwise processed as desired. Alternatively, open ended metallic portions may be utilized to control the amount of sag to which heated glass is subjected, thereby providing glass components of a desired radius of curvature. When metal framed optical components are secured in lasers by weldment, controlled crimping and deflection of the metallic laser jacket portion is utilized for precise alignment of the instrument.
