The Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) will have a high throughput, wide field, optical and I-band camera (WFC), a critically sampled high resolution camera (HRC), and a high throughput, moderate field of view far ultraviolet, solar-blind camera (SBC). The key characteristics of the ACS are listed in Table 1. The throughputs include the geometrical, scattering, and reflectivity losses from the HST optical telescope assembly (Burrows, HST OTA Handbook). Two figures are listed for the ACS efficiencies. The first is the efficiency using the quantum efficiency (QE) of the Scientific Imaging Technologies (SITe) 2K x 4K WFC CCDs and the SITe HRC 1K ´ 1K CCDs selected for the first build of the flight cameras. The second and higher efficiencies are those achieved with SITe CCDs processed and anti-reflection coated at Steward Observatory by Dr. Michael Lesser. We plan to use these better CCDs for the second build of the flight cameras.
