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.

Lens systems and methods of manufacture

Camera lens barrel

Light weight lens barrel systems and methods are provided. In one example, an imaging device includes a lens barrel including a body and a plurality of focusing fins extending from the body. The imaging device further includes a lens system disposed within the lens barrel and configured to receive electromagnetic radiation and direct the electromagnetic radiation. The imaging device further includes a detector array including a plurality of detectors. Each of the plurality of detectors is configured to receive the electromagnetic radiation from the lens system and generate an image based on the electromagnetic radiation. Related methods and systems are also provided.

Light weight lens barrel systems and methods

An optical barrel assembly includes a barrel having an inner bottom surface and an inner lateral surface extending from the inner bottom surface, the inner bottom and lateral surfaces defining a cylindrical housing, and a first element surrounded by the inner lateral surface of the barrel, wherein an outer perimeter of the first element has a different shape than a perimeter defined by the cylindrical housing.
