Issue Date: | 2018 | Volume: | Space Telescopes and Instrumentation 2018: Ultraviolet to Gamma Ray | Editors: | den Herder, Jan-Willem A.; Nikzad, Shouleh; Nakazawa, Kazuhiro | Series: | PROCEEDINGS OF SPIE | Number: | 10699 | First Page: | 1069911 | Abstract: | Lynx is an X-ray mission concept with superb imaging capabilities (< 1arcsec Half Energy Width, HEW) and large throughput (2 m<SUP>2</SUP> effective area @1keV). Several approaches are being considered to meet the challenging technological task of the mirror fabrication. Thin and light substrates are necessary to meet mass constraints. Monolithic fused silica shells are a possible solution if their thickness can be maintained to below 4 mm for mirror shells up to 3 m diameter. In this paper we present the opto-mechanical design of the mirror assembly, the technological processes, and the results achieved so far on a prototypal shells under development. In particular, emphasis is placed on the figuring process that is based on direct polishing and on ion beam figuring and on a temporary stiffening structure designed to support the shell during the figuring and polishing operations and to manage the handling of the shell through all phases up to integration into the telescope supporting structure. | Conference Name: | Space Telescopes and Instrumentation 2018: Ultraviolet to Gamma Ray | Conference Place: | Austin, Texas, United States | Conference Date: | 10-15 June, 2018 | URI: | http://hdl.handle.net/20.500.12386/30098 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10699/2313541/Lynx-optics-based-on-full-monolithic-shells--design-and/10.1117/12.2313541.full?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510619517 9781510619524 |
