Patent number: 6668588Abstract: A method for molding a chalcogenide glass lens includes providing a mold. A preformed lens of chalcogenide glass is placed within the mold. The lens has a top surface and a bottom surface. An amount of chalcogenide glass is deposited within the mold and on the top surface of the preformed lens. The mold is heated, such that the chalcogenide glass on the top surface of the preformed lens softens, melts, and bonds to the top surface of the preformed lens. A lens surface is formed in the melted chalcogenide glass to form a molded lens which is bonded to the top surface of the preformed lens. The molded lens and preformed lens assembly is then removed from the mold.Type: GrantFiled: June 6, 2002Date of Patent: December 30, 2003Assignee: Amorphous Materials, Inc.Inventors: Albert Ray Hilton, II, Albert Ray Hilton, III, William S.

Patent number: 6282922Abstract: The method of the invention provides that a predetermined quantity of molten glass necessary for producing molded glass bodies according to the press-molding method is poured into a press mold prior to the insertion of the molding plug while the press mold is located in the press station, and that the molded glass body is removed after the molding plug is withdrawn from the press mold, with this mold likewise being located in the pressing station.

Patent number: 5992179Abstract: A method of manufacturing an optical device having a profile of refractive indices along its optical axis. A desired volume of each of a plurality of types of optical material are dispensed into a mold of known plan area in the form of a frit or a melt and the mold is heated to cause the materials to melt and fuse together to define a contiguous body of optical material having a desired profile. As the optical materials melt, the different types of material separate out so that they are arranged with the most dense material closest to the bottom of the mold and the least dense material closest to the top of the mold. To enhance this effect, the optical materials are layered in the mold in decreasing order of density of the materials from the bottom to the top so that the layers of optical material with the greater densities are closer to the bottom of the mold than the layers of materials with lesser densities.Type: GrantFiled: May 19, 1997Date of Patent: November 30, 1999Assignee: Light Path Technologies, Inc.Inventors: Xiaojie Xu, Michael E.

Patent number: 4842627Abstract: A method for the manufacture of a preform of barium containing heavy metal fluoride glass comprising a core and a jacket for drawing infrared light waveguides for optical communications technology by casting molten glass onto a predetermined body of solid glass. Hitherto, such a method was executed such that molten core glass was cast into a tube of jacket glass. In order to achieve thicker preforms, one proceeds such here that a solid row of the core glass is surrounded with molten jacket glass. The boundary surface between core and jacket of the generated preform can be improved in the method disclosed herein that the surface of the solid rod is etched before being surrounded with the jacket glass. A nearly perfect boundary surface is obtained by etching with a ZrOCl.sub.2 solution.Type: GrantFiled: June 20, 1988Date of Patent: June 27, 1989Assignee: Siemens AktiengesellschaftInventors: Hartmut Schneider, Achim Schoberth

Patent number: 4685200Abstract: A technique for enclosing microelectronic circuit elements in hermetically sealed packages comprising a planar ceramic substrate with a box-like ceramic cover sealed thereto by a fused glass coating. The glass sealant is applied to the substrate in the form of a paste which thereafter is fired at high temperature and cooled to produce a smooth glass coating. With the cover in place on the substrate, the glass coating is remelted by heat developed by infra-red radiation developed by four line-focussed radiant heaters at the four sides of the package. The radiation of each heater is focussed at the interface line between the cover and the substrate. Because the radiant heat is concentrated along the interface line, unwanted heat transfer into the package is minimized, and the temperature is prevented from rising sufficiently to damage heat-sensitive elements.Type: GrantFiled: January 18, 1982Date of Patent: August 11, 1987Assignee: Analog Devices, IncorporatedInventor: Delip R.
