The developed technique is based on modular elements, named X-ray Optical Units (XOUs), made of several layers of thin foils of glass, previously formed by direct hot slumping in cylindrical configuration, and then stacked in a Wolter-I configuration, through interfacing ribs. The achievable global angular resolution of the optics relies on the surface shape accuracy of the slumped foils, on the smoothness of the mirror surfaces and on the correct integration and co-alignment of the mirror segments achieved with a dedicated Integration Machine (IMA). In this paper we provide an update of the project development, reporting on the last results achieved. In particular, we will present the results obtained with full illumination X-ray tests for the last developed prototypes. | Titolo del convegno: | SPIE Optical Engineering + Applications, 2015 | Luogo del convegno: | San Diego, CA, USA | Periodo del convegno: | 9-13 August, 2015 | URI: | http://hdl.handle.net/20.500.12386/23531 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9603/1/Slumped-glass-optics-with-interfacing-ribs-for-high-angular-resolution/10.1117/12.2188598.short?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781628417692 | DOI: | 10.1117/12.2188598 | Bibcode ADS: | 2015SPIE.9603E..0PC | Fulltext: | open |
