Paper Abstract

The demand for larger collecting areas in X-ray telescopes within the mass limits of the launcher creates the need for light-weight mirror materials. At our institute we develop the technology of indirect thermal slumping of thin glass sheets to manufacture light mirror segments. A crucial part of the development is the measurement of the glass surface, shape and thickness profile in order to evaluate the quality of the reproduction method. We describe the measurement set-up, the analysis method of the surface profile and the evaluation of thickness variations in the glass, as well as their influence on the final glass sheets.
