Science filter performance summary for the Roman Space Telescope Wide Field Instrument

Abstract

The Wide Field Instrument (WFI) on NASA's Roman Space Telescope has eight filters on a large filter wheel that are key to enabling the science missions of the observatory. These filters have completed their journey from individual components to fully integrated elements in the optical element wheel assembly (EWA), and have been characterized in terms of their transmittance, wavefront impact, and other key performance characteristics. This paper will summarize their capabilities and performance, demonstrating their ability to deliver top-quality science on orbit.
