Fermi, 5, I-50125 Firenze, Italy Received August 11,1994; accepted July 17,1995 Abstract. - The Arcetri near-infrared camera ARNICA was built as a users instrument for the Infrared Telescope at Gornergrat (TIRGO), and is based on a 256 x 256 NICMOS 3 detector. In this paper, we discuss ARNICA's optical and astronomical performance at the TIRGO and at the William Herschel Telescope on La Palma. Optical performance is evaluated in terms of plate scale, distortion, point spread function, and ghosting. Astronomical performance is characterized by camera efficiency, sensitivity, and spatial uniformity of the photometry. Key words: infrared: general - techniques: photometric - instrumentation: detectors
