title: Wolter-schwarzschild telescopes for x-ray astronomy.
abstract: The resolution of a Wolter-Schwarzschild telescope is intrinsically superior to the resolution of the corresponding paraboloid-hyperboloid telescope. The improvement is important for high resolution and wide field telescope designs having grazing angles larger than about 1.5 degrees .
