Abstract

A quarter-meter diameter, modified Ritchey-Chretien camera is described for spacecraft based observation of Halley's Comet. The system will operate over an unusually broad spectral region, from 0.121 6 um (the hydrogen Lyman-alpha line) to 1.1 pm using reflective primary and secondary mirror optics and a thin UV-grade lithium fluoride (LiF) refractive element as a field corrector near the image plane. The f/12, 3000 mm focal length camera has a 0.4° full field of view for operation with a 15 X 15 mm charge-coupled device (CCD) detector array. The UV-enhanced silicon CCD detector is a 1000 X 1000 array of 15 um pixels which establishes the system resolution requirement. The optical design and performance are discussed, with an emphasis on the image analysis with respect to pixel resolution elements used for viewing extended objects such as comets.
