  • Lens systems and methods of manufacture
    Patent number: 12253657
    Abstract: Systems and methods according to one or more embodiments are provided for annealing a chalcogenide lens at an elevated temperature to accelerate release of internal stress within the chalcogenide lens caused during a molding process that formed the chalcogenide lens. In particular, the annealing process includes gradually heating the chalcogenide lens to a dwell temperature, maintaining the chalcogenide lens at the dwell temperature for a predetermined period of time, and gradually cooling the chalcogenide lens from the dwell temperature. The annealing process stabilizes the shape, the effective focal length, and/or the modulation transfer function of the chalcogenide lens. Associated optical assemblies and infrared imaging devices are also described.
    Type: Grant
    Filed: August 12, 2022
    Date of Patent: March 18, 2025
    Assignee: Teledyne FLIR Commercial Systems, Inc.
    Inventors: Alan D. Kathman, William J. Hall, Erika Goransson, Todd E. Rixman, Bengt Jervmo, Bo Dahllof, Stefan Gustavsson, Leif Sommar, Olof Holmgren, Hans Ostling
