Abstract

One of the most challenging tasks for future X-ray observatories is the enhancement of collecting area combined with very good angular resolution. Light-weight mirror materials, such as thin glass sheets, are needed to achieve this aims within the mass limits. We are developing a technology based on indirect hot slumping of thin glass segments. This technique enables us to produce the parabolic and hyperbolic part of the Wolter type I mirrors in one piece. Currently we focus on a combination of a ceramic slumping mould and glass type D263. The experimental set-up in our laboratories as well as the slumping process are described in detail; furthermore we report on the metrology methods used for measuring the glass sheets and moulds. Finally the results of the X-ray tests of several integrated glass sheets are presented.
