Wide-Field Camera 3 (WFC3), a panchromatic imager being developed for the Hubble Space Telescope (HST), is now fully integrated and over the past 9 months has completed first rounds of extensive ground testing at Goddard Space Flight Center, in both ambient and thermal-vacuum test environments. The thermal-vacuum testing marks the first time that both of the WFC3's UV/Visible and IR channels have undergone testing and characterization in flight-like operating conditions. A full suite of calibration tests have been performed, including dark current, read noise, flatfield, detector gain, linearity, system throughput, encircled energy, grism dispersion, and IR thermal background measurements. This report summarizes the results of these tests and their implications for the on-orbit scientific performance of WFC3.
