Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
128 words
A method of manufacturing laser components comprising the steps of: providing a plurality of metallic annular elements interconnected in an integral matrix structure; placing said matrix elements between top and bottom mold portions to define cavities around each of said annular elements, each cavity closing against the corresponding annular element between the inner and outer circumference thereof, for partial overlap by the mold portions of each annular element; providing glass slugs in each of said cavities; melting and cooling said slugs to conform to the shape of said cavities, thereby partially to overlap each associated annular element with glass; optically finishing said glass; and separating each element from the matrix at points which were overlapped by said mold portions and which therefore were not overlapped by melted glass.
Claim 2
Independent Claim
128 words
A method of manufacturing laser components comprising the steps of: providing a plurality of metallic annular elements interconnected in an integral matrix structure; placing said matrix elements between top and bottom mold portions to define cavities around each of said annular elements, each cavity closing against the corresponding annular element between the inner and outer circumference thereof, for partial overlap by the mold portions of each annular element; providing glass slugs in each of said cavities; melting and cooling said slugs to conform to the shape of said cavities, thereby partially to overlap each associated annular element with glass; optically finishing said glass; and separating each element from the matrix at points which were overlapped by said mold portions and which therefore were not overlapped by melted glass.
Claim 3
Dependent Claim
34 words
A method as in claim 1 wherein said finishing step comprises: mounting said matrix on polishing fixture; grinding all glass portions to a desired configuration; and polishing all glass portions to a desired finish.
Claim 4
Dependent Claim
23 words
A method as in claim 1 wherein the slugs are composed of a material compatible for bonding with the metal of said matrix.
