Abstract
Wide Field Camera 3 (WFC3) is a powerful new imager recently installed on the Hubble Space Telescope during Servicing Mission 4. WFC3 covers wavelengths from the near UV (200nm) to the near infrared (out to 1.7microns), in two channels. The UV/visible (UVIS) channel utilizes two low-noise, UV-enhanced 2Kx4K CCD detectors from e2v, while the IR channel incorporates a 1Kx1K 1.7micron cutoff HgCdTe array, custom-developed for the WFC3 program by Teledyne. We report here on the performance of the detectors in-flight as observed in this summer's Servicing Mission Orbital Verification program.
