INFOCµS is a balloon-borne instrument incorporating recent breakthroughs in focusing optics and detectors to achieve order of magnitude improvements in both hard X-ray sensitivity and imaging resolution, with high resolution spectroscopy. This instrument is a pioneering effort to extend into the hard X-ray energy range the power of focusing optics that has revolutionized X-ray astronomy with missions like ROSAT and ASCA.
The telescope is conical approximation of Wolter-I optics with 8m focal length and 40cm diameter. It employed 255 nested ultra-thin reflector pairs, or supermirrors that reflected hard X-rays by Bragg reflection at incidence angles larger than the critical angle of total external reflection.
