According to the scientific requirements of eXTP, optical thermal filters with aluminized polyimide (PI) film structure had been designed and tested in this paper, the results of mechanical tests including burst pressure, vibration and acoustic tests, also the transparent properties of optics in UV, Vis and IR lights are presented. The mechanical test results show that the filters for LAD and SFA can't pass the acoustic tests, causing the thickness of PI should be increased or a nickel mesh structure should be added. Furthermore, the transmission test results indicate that a single-sided Al deposited structure is more suitable than a double-sided one. | Titolo del convegno: | Space Telescopes and Instrumentation 2020: Ultraviolet to Gamma Ray | Periodo del convegno: | 14-18 December, 2020 | URI: | http://hdl.handle.net/20.500.12386/34441 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/11444/2562041/Optical-thermal-filters-for-eXTP-manufacturing-and-characterization/10.1117/12.2562041.short?SSO=1 https://api.elsevier.com/content/abstract/scopus_id/85099303637 |
