Wide-Field Camera 3 (WFC3) is an instrument currently being developed for installation on the Hubble Space Telescope (HST) during its fourth Servicing Mission (currently scheduled for late 2003). The instrument will contain two imaging channels. The UVIS channel covers from 200 nm to 1000 nm using a UV-sensitized CCD detector. The IR channel covers from 850 nm to 1700 nm using a Rockwell Mercury-Cadmium-Telluride (MCT) focal plane array. After deployment, this instrument will provide HST with a significant improvement in sensitivity in both the near-UV and near-IR spectral regions.
