Abstract
MIRAC is a Mid-InfraRed Array Camera built for ground-based astronomy by Steward Observatory at the University of Arizona, Harvard Smithsonian Center for Astrophysics, and the Center for Advanced Space Sensing at the Naval Research Laboratory. It utilizes a Hughes Aircraft Co. 20 × 64 pixel arsenic-doped silicon impurity-band-conduction hybrid array with a capacitance-transimpedance-amplifierreadout (CRC 444A). The detector has an operating wavelength range of 2–26 μm. The camera has been operated on the Steward Observatory 1.5- and 2.3-m and the NASA 3-m IRTF telescopes to observe a variety of sources including solar system objects, young stellar objects, planetary nebulae, infrared-luminous galaxies, star forming regions, and brown dwarfs.
