The CZT detector on the Infocus hard X-ray telescope is a pixellated solid-state device capable of imaging spectroscopy by measuring the position and energy of each incoming photon. The detector sits at the focal point of an 8m focal length multi-layered grazing incidence X-ray mirror, and is sensitive to photons with energies between 20 and 40 keV. The detector has an energy resolution of 5 keV at 30 keV, and the Infocus telescope has an angular resolution of 1 arcminute and a field of view of about 10 arcminutes. Infocus flew on a balloon mission in July 2001 and observed Cygnus X-1. We present results from laboratory testing of the detector, and a hard X-ray spectrum and image of Cygnus X-1 obtained with Infocus.
