ABSTRACT:
A catoptric zoom optical device comprising a plurality of axially-spaced reflectors disposed in a set for receiving and reflecting energy from an object in the ultraviolet through infrared spectrum to generate a real image of the object and support and drive apparatus for selectively varying the effective focal length of the reflector set to magnify the image and for selectively varying the axial distance between the reflector set and a detector of the image for focusing the image on the detector.
