The HST focal plane, showing the instrument complement after Servicing Mission 4. The WFC3 UVIS and IR channels view the same patch of sky, but not simultaneously. All instrument apertures are shown to scale, except for COS, which has been enlarged by a factor of five for clarity.

NASA"s new Wide Field Camera 3 has been built for installation during HST Servicing Mission 4. Equipped with state-of-the-art detectors and optics, WFC3 will provide wide-field imaging with continuous spectral coverage from the ultraviolet into the infrared, dramatically increasing both the survey power and the panchromatic science capabilities of HST.

The discovery efficiency of the HST cameras. Here, the discovery efficiency is proportional to the total system throughput at the pivot wavelength of the broadband filters and proportional to the field of view.
