Paper Abstract

Future large X-ray telescopes will be based on segmented designs and will require different techniques for error analysis and budgeting from those used for full shell optics. In this paper we develop a grazing incidence optical model using commercial software Zemax for figure error compensation. In particular we show how the image of a pair of mirror segments with average radius and/or average cone angle errors can be optimized with rigid body motions such as pitch, radial despace and axial despace. We show detailed tolerance analysis of the optical model and present results on how to compensate for these errors up to limitations determined by mechanical constraints of the telescope module.
