Design evolution of the Giant Magellan Telescope Integral Field Spectrograph, GMTIFS
2018
Ground-based and Airborne Instrumentation for Astronomy VII
We report the design evolution for the GMT Integral Field Spectrograph, (GMTIFS). To support the range of operating modes -a spectroscopic channel providing integral field spectroscopy with variable spaxel scales, and a parallel imaging channel Nyquist sampling the LTAO corrected field of view -the design process has focused on risk mitigation for the demanding operational tolerances. We summarise results from prototype components, confirming concepts are meeting the necessary specifications.
