Paper Abstract

FORCAST has been selected to be the "first light" U.S. science instrument aboard SOFIA. FORCAST will offer dual channel imaging in discrete filters at 5 - 25 microns and 30 - 40 microns, with diffraction-limited imaging at wavelengths > 15 microns. FORCAST will have a plate scale of 0.75 arcsec per pixel, giving it a 3.2 arcmin x 3.2 arcmin FOV on SOFIA. We give a status update on FORCAST, including filter configuration for SOFIA's early science phase; anticipated in-flight performance; SOFIA facility testing with FORCAST; ground-based testing performance at Palomar Observatory; performance of its new dichroic beamsplitter; and a preliminary design of the in-flight calibration box.
