Abstract: A mount connects a light emitting device, such as a laser diode assembly, to an optical bench. The mount may include a thermoelectrical module coupled to a sub-element of a heat exchanger extending through an opening formed in the optical bench. The thermoelectrical module acts as a heat sink to draw heat outwardly from the laser diode and cool the same. The heat sink enables the laser diode to transmit heat thereto such that substantially all of the heat generated by the laser diode sinks to the heat exchanger. As such, the laser diode transfers virtually no heat to the optical bench so the optical bench is free of deflections or distortions resultant from the heat generated during generation of the laser beam.

Abstract: An optical assembly is part of an optical system such as a laser communication system on a moveable platform that operates in a range of temperature extremes. The optical assembly has a mount with a plurality of supports that couple an optical mirror to a frame or chassis of the optical system. The supports may be selectively heated or cooled in accordance with their respective coefficients of thermal expansion to reduce, minimize, or eliminate angular drift of the mounted optic or mount. The supports expand or contract to correct for misalignments of the beam reflection angle to improve the accuracy and efficiency of the optical system without significantly increasing size, weight, and power of the optical system.

Abstract: The present disclosure relates to a system and method for verifying a diopter setting and range of an optical system eyepiece by utilizing an image sensor to view and analyze test patterns of spots displayed within the optical system eyepiece and calculating the diopter setting and range of the optical system eyepiece from an observed change in the test pattern at different diopter settings.
