Overview

The IRIS2 infrared imager and spectrograph was built in-house by the AAO, and commissioned between October 2001 and July 2002. It provides the AAO with an infrared facility for

  • Wide field imaging (~8'x8') with a pixel scale of 0.4486"/pixel
  • Moderate resolution (R=2400) long-slit spectroscopy, and
  • Moderate resolution (R=2400) multi-object spectroscopy. 

If you have any queries about the status or use of IRIS2, please do not hesitate to contact the Instrument Scientist, Chris Lidman (chris.lidman@aao.gov.au).

Papers making use of data from IRIS2 should refer to the IRIS2 technical description by Tinney et al. 2004 (Proc. SPIE, 5492, 998).
