  • Infrared detector comprising an evacuated and cooled Dewar having an elliptical spheroid end window
    Patent number: 4937450
    Abstract: The evacuated and cooled Dewar 1 of an infrared detector has a window end in the shape of an elliptical spheroid, and an IR detection element 3 is mounted within the focal circle of the spheroid. The construction minimizes the sensing of spurious IR rays by the detection element, as well as the heat load for the coolant and the cool down time.
