The initial results of a study on Cassegrain-type telescopes, optimized for astrometric applications, are presented. Two similar designs were optimized for minimum distortion, and the results are compared to those obtained for a one-mirror telescope with the same focal length and focal ratio. The results show that the two-mirror systems as well as the one-mirror system are virtually distortionfree, when perfectly aligned. The effects of various misalignments on the state of correction are also investgated.
