Scientific paper

ARNICA (ARcetri Near Infrared CAmera) is the imaging camera for the near infrared bands between 1.0 and 2.5 micrometer that Arcetri Observatory has designed and built as a common use instrument for the TIRGO telescope (1.5 m diameter, f/20) located at Gornergrat (Switzerland). The scale is 1 sec per pixel, with sky coverage of more than 4 min x 4 min on the NICMOS 3 (256 x 256 pixels, 40 micrometer side) detector array. The optical path is compact enough to be enclosed in a 25.4 cm diameter dewar; the working temperature of detector and optics is 76 K. We give an estimate of performance, in terms of sensitivity with an assigned observing time, along with some preliminary considerations on photometric accuracy.
