The Infrared Camera (IRC) is one of the focal-plane instruments on board ASTRO-F(also called as the Infrared Imaging Surveyor; IRIS) and will make imaging and low-resolutionspectroscopy observations over a wide spectral range in the near- to mid-infrared from 2 - 26μm.The IRC will be operated in the pointed observation mode of ASTRO-F to make deep photometricand spectroscopic surveys of wide field-of-views. It will provide a significant database for studiesof the formation and evolution of galaxies, properties of brown dwarfs, evolution of planetarysystems, and processes of star formation. The IRC comprises three chan NIR (2 - 5μm),MIR-S (5 - 12μm) and MIR-L (12 - 26μm), and employs state-of-the-art large format arraydetectors. The NIR channel uses a 512×412 InSb array and the MIR channels adopt 256×256Si:As impurity band conduction (IBC) arrays. Each channel has a field-of-view of 10′×10′with anearly diffraction-limited spatial resolution. The NIR and MIR-S channels simultaneously observethe same field on the sky, while the MIR-L observes the sky about 200 away from the NIR/MIR-Sposition. The design overview and current development status of the IRC are presented.
