Abstract : The antinarcissus reflector assembly comprises: a cold stop subassembly that includes an aperture; and a concave spherical mirror having an opening, and also having a center of curvature at the center of the aperture of the cold stop subassembly. Unlike in the prior art devices, the only cold surface that is seen by the optics ahead of the detector is the face portion thereof, which shows through the opening in the concave spherical mirror, rather than reflections of the interior of the cold stop subassembly. Therefore, the undesirable diffused, cool patch which appears in the center of the picture when prior art devices are used is eliminated or, at the very least, is minimized. (Author)
