title: Design Parameters of Paraboloid-Hyperboloid Telescopes for X-ray Astronomy.
abstract: We have evaluated the principal optical characteristics of paraboloid-hyperboloid x-ray telescopes by a ray-tracing procedure; we find that our results for resolution, focal plane curvature, and finite source distance effects may be approximated in terms of the design parameters by simple empirical formulas.
