[90.03] Status of the HST Wide Field Camera 3

J.W. MacKenty (STScI), R.A. Kimble (NASA/GSFC), WFC3 Team

The Wide Field Camera 3 is under construction for a planned deployment in the Hubble Space Telescope during Servicing Mission 4 in early 2004. WFC3 will replace the aging WFPC2 instrument in the HST radial bay. WFC3 provides two imaging channels. The UVIS channel features a 4096 x 4096 pixel CCD focal plane with sensitivity from 200 to 1000 nm. Equipped with 47 filters and an ultraviolet grism, the UVIS channel provides unprecented sensitivity and field of view in the near ultraviolet for HST. The IR channel features a 1014 x 1014 pixel HgCdTe focal plane covering 850 to 1700 nm. With 17 filters and 2 grisms, this provides HST with a powerful near infrared capability. We report on the status of the development and testing of WFC3. We present results on the testing of the optics, filters, detectors, and instrument systems. In anticipation that the Fall 2003 Call for Cycle 13 HST observations will include the opportunity to propose investigations with WFC3, we provide an updated estimate of its system level performance.
