Title: | Final design and construction of the ERIS calibration unit | Authors: | DOLCI, Mauro DI RICO, Gianluca VALENTINI, Angelo DI CIANNO, Amico DI ANTONIO, IVAN RICCARDI, Armando FERRUZZI, Debora ESPOSITO, Simone |
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: | 107023G | Abstract: | The Calibration Unit (CU) is a subsystem of the Enhanced Resolution Imager and Spectrograph (ERIS), the newgeneration instrument for the Cassegrain focus of the ESO UT4/VLT, aimed at performing AO-assisted imaging and medium resolution spectroscopy in the 1-5 micron wavelength range. The ERIS-CU is aimed to providing both focal plane artificial sources and uniform illumination over the 0.4 - 2.4 micron wavelengh range, for purposes of calibration and technical check of the SPIFFIER spectrograph, the NIX camera and the AO Module. Some challenging aspects emerged during the detailed design phase, mainly related to the need to cover such a broad wavelength range while ensuring adequate photon rates, excellent image quality and high Strehl. The technical solutions adopted to achieve the final design goals are presented and their implementation during the construction phase are shown and discussed. | Conference Name: | Ground-based and Airborne Instrumentation for Astronomy VII | Conference Place: | Austin, Texas (US) | Conference Date: | 10-15 June, 2018 | URI: | http://hdl.handle.net/20.500.12386/30857 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10702/2313996/Final-design-and-construction-of-the-ERIS-calibration-unit/10.1117/12.2313996.full?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510619579 9781510619586 |
