Spectral Characterization of the Roman Space Telescope Grism and Prism Slitless Spectrometers


The RST Grism and Prism assemblies will provide the Wide-Field Instrument (WFI) with the ability to perform slitless, multi-object spectroscopy across the complete field of view. These optical elements play a critical role in the High Latitude Wide Area and High Latitude Time Domain Surveys, which are expected to produce robust spectroscopic redshifts for tens of millions of objects over the mission lifetime. This presentation will go over the methods used to characterize these assemblies, as well as a highlight reel of some of the most notable (and some surprising!) results.
