Given the fast-track nature of this mission, we developed a non-flying Demonstration Model, whose optics are flight representative and whose mechanics provides the same interfaces of the flight model, but is not thermally representative. In this paper, we describe CHEOPS Demonstration Model handling, integration, tests, alignment and characterization, emphasizing the verification of the uncertainties in the optical quality measurements introduced by the starlight simulator and the way the alignment and optical surfaces are measured. | Conference Name: | Space Telescopes and Instrumentation 2016: Optical, Infrared, and Millimeter Wave | Conference Place: | Edinburgh, United Kingdom | Conference Date: | 26 June - 1 July 2016 | URI: | http://hdl.handle.net/20.500.12386/26306 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9904/990439/Aligning-the-demonstration-model-of-CHEOPS/10.1117/12.2232136.short | ISSN: | 0277-786X | ISBN: | 9781510601871 | DOI: | 10.1117/12.2232136 | Bibcode ADS: | 2016SPIE.9904E..39B | Fulltext: | open |
