HRCAM Specifications

The HRCAM uses a thinned, backside illuminated Loral CCD. A quantum efficiency test was performed prior to integration and shows a peak QE of 97% at 5000Å.  An Atmospheric Dispersion Corrector is available which limits image elongation to less than 0.05 " down to 15° above the horizon. The focal plane contains the pick-off mirror for the AO guiding at 11.67 " from the optical axis in x and y.
