Issue Date: | 2018 | Volume: | Ground-based and Airborne Instrumentation for Astronomy VII | Editors: | Evans, Christopher J.; Simard, Luc; Takami, Hideki | Series: | PROCEEDINGS OF SPIE | Number: | 10702 | First Page: | 107028U | Abstract: | The paper describes the preliminary design of the MICADO calibration assembly. MICADO, the Multi-AO Imaging CAmera for Deep Observations, is targeted to be one of the first light instruments of the Extremely Large Telescope (ELT) and it will embrace imaging, spectroscopic and astrometric capabilities including their calibration. The astrometric requirements are particularly ambitious aiming for 50 μas differential precision within and between single epochs. The MICADO Calibration Assembly (MCA) shall deliver flat-field, wavelength and astrometric calibration and it will support the instrument alignment to the Single-Conjugate Adaptive Optics wavefront sensor. After a complete overview of the MCA subsystems, their functionalities, design and status, we will concentrate on the ongoing prototype testing of the most challenging components. Particular emphasis is put on the development and test of the Warm Astrometric Mask (WAM) for the calibration of the optical distortions within MICADO and MAORY, the multiconjugate AO module. | Conference Name: | Ground-based and Airborne Instrumentation for Astronomy VII | Conference Place: | Austin, Texas, United States | Conference Date: | 10-15 June, 2018 | URI: | http://hdl.handle.net/20.500.12386/29459 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10702/2311721/The-MICADO-first-light-imager-for-the-ELT--preliminary/10.1117/12.2311721.full?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510619586 | DOI: | 10.1117/12.2311721 | Bibcode ADS: | 2018SPIE10702E..8UR | Fulltext: | open |
