Title: | ELT-HIRES the high resolution instrument for the ELT: optical design and instrument architecture | Authors: | OLIVA, Ernesto TOZZI, Andrea FERRUZZI, Debora RIVA, Marco Genoni, Matteo Marconi, Alessandro Maiolino, R. ORIGLIA, Livia |
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: | 107028O | Abstract: | The first generation of ELT instruments will include an optical-infrared High Resolution Spectrograph, conventionally indicated as ELT-HIRES. This paper describes the optical design and overall architecture of the instrument whose main capabilities can be summarized as follows. - Fibers fed specrographs with resolving power R=100,000 (HR-modes), R=150,000 (UHR-modes) and R=20,000 (MR-modes). - Simultaneous wavelength coverage from 400 nm to 1800 nm; extendable to 300-2400 nm. - Spectrometers with fixed configurations and without moving optical parts. - Maximum size of entrance apertures ideal for seeing limited observations. - Many observing modes, including seeing-limited single-object spectroscopy, multi-objects medium resolution spectroscopy and IFU observations with different spatial scales, down to the diffraction limit of the ELT telescope. - Observing modes defined and selected in interfaces outside of the spectrographs. - Modular design compatible with a minimal baseline that can be subsequently expanded and upgraded. | 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/20.500.12386/27967 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10702/2309923/ELT-HIRES-the-high-resolution-instrument-for-the-ELT/10.1117/12.2309923.full | ISSN: | 0277-786X | ISBN: | 9781510619586 | DOI: | 10.1117/12.2309923 | Bibcode ADS: | 2018SPIE10702E..8OO | Fulltext: | open |
