Abstract Information:

The Infrared Imaging System (IRIS) is a 0.8m telescope and a 1024x1024 pixels camera (IRISCAM) with a HAWAII-1 detector array. IRIS is located at the Cerro Armazones Observatory in Chile that is operated by the Ruhr University Bochum jointly with the Universidad Católica del Norte in Antofagasta. The IRISCAM is a refurbished version of the old University of Hawaii QUIRC camera, equipped with new optics to match the IRIS telescope.

IRIS is being used primarily to survey star-forming regions for variability. The goal is to discover young stellar objects undergoing accretion instabilities or rotational modulation of star spots, eclipsing binaries, and variable reflection nebulae.

The telescope and the infrared camera are completed and first light was achieved in May of 2010. IRIS is currently transitioning to fully robotic operation. This paper describes the design of the IRIS system and the experience during the testing and commissioning phase.
