The main scientific goal of PLATO is the discovery and study of extrasolar planetary systems by means of planetary transits detection. According to the current baseline, the scientific payload consists of 34 all refractive telescopes having small aperture (120mm) and wide field of view (diameter greater than 37 degrees) observing over 0.5-1 micron wavelength band. The telescopes are mounted on a common optical bench and are divided in four families of eight telescopes with an overlapping line-of-sight in order to maximize the science return. Remaining two telescopes will be dedicated to support on-board star-tracking system and will be specialized on two different photometric bands for science purposes. The performance requirement, adopted as merit function during the analysis, is specified as 90% enclosed energy contained in a square having size 2 pixels over the whole field of view with a depth of focus of +/-20 micron. Given the complexity of the system, we have followed a Montecarlo analysis approach for manufacturing and alignment tolerances. We will describe here the tolerance method and the preliminary results, speculating on the assumed risks and expected performances. | Titolo del convegno: | Space Telescopes and Instrumentation 2016: Optical, Infrared, and Millimeter Wave | Luogo del convegno: | Edinburgh, UK | Periodo del convegno: | 26 June-1 July, 2016 | URI: | http://hdl.handle.net/20.500.12386/25218 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9904/1/Manufacturing-and-alignment-tolerance-analysis-through-Montecarlo-approach-for-PLATO/10.1117/12.2232565.full | ISSN: | 0277-786X | ISBN: | 9781510601871 | DOI: | 10.1117/12.2232565 | Bibcode ADS: | 2016SPIE.9904E..2ZM | Fulltext: | open |
