Paper Abstract

Many large optical telescopes have a wide field camera as one of their primary instruments. Camera designs with all reflective surfaces are useful because they give stable image quality over a broad spectral band. Systems with two conic mirrors can correct the residual aberrations, field curvature and astigmatism, of Ritchey-Chretien telescopes. We present first- and third-order optical design relations which can facilitate the formation of design concepts during preliminary trade studies. We apply the relations to the Hubble Space Telescope in the design of a new wide field camera which compensates the existing spherical aberration, as well as the astigmatism and field curvature, of the telescope.
