Optical design of the WFIRST Phase-A Wide Field Instrument

The WFIRST Wide-Field Infrared Survey Telescope TMA optical design provides 0.28-sq° FOV at 0.11” pixel scale, operating between 0.48-2.0µm, including a spectrograph mode (0.95-1.9µm.) An IFC provides 2-D discrete spectroscopy at 0.15” & 0.3” sampling.
