Abstract: An assembly and method for installing a viewing window into a single hole in a panel of an enclosure from a single side. A viewing window assembly comprises actuators and attachment members configurable to allow the attachment members to pass through a hole in a panel from a front side. Upon actuation of the actuators, the attachment members may engage one or both of the back surface of the panel and the inner edge of the hole therein in order to secure the window assembly to the panel.

Abstract: A thermal imaging camera may be used to capture a visible-light (VL) image and an infrared (IR) image. In some examples, the camera includes adjustable focus IR optics. For example, the camera may include a focus mechanism coupled to the IR optics and configured to move the IR optics to various focus positions so as to focus the IR optics. The various focus positions may include a hyperfocal position in which a scene is in focus between a set distance and infinity, and a plurality of focus positions in which the scene is in focus between the set distance and a minimum focus distance. Depending on the configuration of the camera, the IR optics of the camera may define an F-number greater than 1.0, and an axis of the IR optics may be offset from an axis of the VL optics by a distance less than 1.7 inches.

Abstract: An infrared imaging system having functionality for maintaining image quality in the presence of temperature drift of the system. Such functionality is applied repetitively to maintain image quality of a target scene, yet without continuous actuation of a shutter of the system. The functionality of the imaging system results from implementing an imager algorithm. In use, the imager algorithm functions with a calibration curve created for the imaging system, with the curve comprising a plot of system output versus target scene temperature.
