MUMBAI, India, June 19 -- Intellectual Property India has published a patent application (202617055207 A) filed by Corning Incorporated on April 30, 2026, for Arsenic-Rich, Selenium-Based Chalcogenide Glasses With Ultra-Low Concentrations Of Dopant For Injection Molding.
Inventors include Brown, Jason Allen; and Lindberg, George Paul.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: A precision optical element is disclosed in one or more embodiments. The precision optical element comprises a glass body. The glass body comprises a chalcogenide glass that is substantially similar to a reference chalcogenide glass in terms of chemistry and certain properties. The reference chalcogenide glass is a binary glass in the arsenic-selenium glassy system. The chalcogenide glass comprises arsenic, selenium, and a dopant configured to prevent shear thickening when the glass body is formed via hot-melt processing. The reference chalcogenide glass corresponds to the chalcogenide glass with the dopant removed and with the arsenic and the selenium stoichiometrically rebalanced without the dopant. The reference chalcogenide glass exhibits shear thickening when the glass body is formed with the reference chalcogenide glass via the same hot-melt processing.
