The wide field optical spectrograph (WFOS) for TMT: fiber-WFOS optical design (Conference Presentation)

Optical Conceptual Design for the Giant Magellan Telescope Multi-Object Astronomical and Cosmological Spectrograph

“…Optical wide-field MOS is a highly desirable instrument for the new generation of ELTs due to the large variety of science cases they can address. Each of the three planned ELTs have its own planned optical MOS spectrograph: in the case of the TMT it is the Wide Field Optical Spectrograph, WFOS (Kupke et al, 2018;TMT International Observatory, 2020), for the E-ELT it is the MOSAIC (Fèvre et al, 2010;Hammer et al, 2016;Morris et al, 2018), and for the GMT it is GMACS.…”
