Roman Coronagraph II Part 2: Overview of the Instrument Test Campaign and Key Requirement Verification

NASA’s Nancy Grace Roman Space Telescope includes the Coronagraph Instrument: a technology demonstrator for active coronagraphy that uses deformable mirrors for deep starlight suppression which enables imaging and spectroscopy of nearby faint companions. This paper provides an overview of the Coronagraph Instrument-level test campaign that took place at the Jet Propulsion Laboratory prior to the delivery of this instrument for the Roman payload and observatory integration. This test campaign served to expose the instrument to the environments associated with the Roman launch and space operations, and to verify the Coronagraph Instrument functional and performance requirements in the most comprehensive way possible prior to launch. An overview of the coronagraph requirements and key results of the test campaign will be described.
