Patent number: 10519061Abstract: Disclosed herein are methods for producing glass articles by hot-melt processing techniques. The methods involve the use of arsenic-free chalcogenide glasses. Despite the absence of arsenic, the chalcogenide glasses have low characteristic temperatures and are stable against crystallization. The low characteristic temperatures render the glasses capable of being hot-melt processed using conventional equipment. The glasses disclosed herein are suitable for the fabrication of optical devices, including but not limited to IR-transmitting optical devices.Type: GrantFiled: July 7, 2017Date of Patent: December 31, 2019Assignee: Corning IncorporatedInventors: Bruce Gardiner Aitken, Stephen Charles Currie

Patent number: 8541324Abstract: IR-transmitting alkaline earth selenogallo- and/or selenoindo-germanate glasses that are capable of hosting luminescent rare earth dopants. The relatively high Ga and/or In content of most compositions serves to eliminate the typical clustering tendency of rare earth dopants in chalcogenide glasses, resulting in improved luminescence.Type: GrantFiled: November 29, 2011Date of Patent: September 24, 2013Assignee: Corning IncorporatedInventors: Bruce Gardiner Aitken, Stephen Charles Currie

Patent number: 8449283Abstract: A die for forming an extrusion includes a die body, a body feed section and an extrusion forming section. The die body may include an inlet and an outlet defining an extrudate flow path through the die body. The body feed section may be positioned between the inlet and outlet and includes an arrangement of body feed channels. The extrusion forming section may be positioned between the body feed section and the outlet and includes a thin-wall forming portion fluidly coupled to at least one thick-wall forming portion. The thin-wall forming portion may include an array of pins extending from the body feed section towards the outlet and the thick-wall forming portion may include at least one baffle section positioned in the extrudate flow path through the thick-wall forming portion. The area of the thick-wall forming portion may be greater than an interstitial area between the pins.Type: GrantFiled: June 12, 2009Date of Patent: May 28, 2013Assignee: Corning IncorporatedInventors: Stephen Charles Currie, Mircea Despa, Paul Martin Elliott, Richard Curwood Peterson

The glasses have the general formula YZ, where Y is Ge, As, Sb or a mixture of two or more of the sane; Z is Se, Te, or a mixture of Se+Te; and Y and Z are present in amounts (in atomic/element percent) in the range of Y=15-70% and Z=30-85%. The chalcogenide glasses of the invention have a 10,000 poise temperature of 400° C. and are resistant to crystallization when processed at high shear rates at their 10,000 poise temperature. The glasses can be used to make, among other items, molded telecommunication elements, lenses and infrared sensing devices.Type: GrantFiled: July 10, 2006Date of Patent: February 12, 2008Assignee: Corning IncorporatedInventors: Bruce Gardiner Aitken, Stephen Charles Currie, Beth Costello Monahan, Lung-Ming Wu, Everett William Coonan
