UNSWIRF: A Tunable Imaging Spectrometer for the Near-Infrared
Abstract
We describe the specifications, characteristics, calibration, and analysis of data from the University of New South Wales Infrared Fabry-Perot (UNSWIRF) etalon. UNSWIRF is a near-infrared tunable imaging spectrometer, used primarily in conjunction with IRIS on the AAT, but suitable for use as a visitor instrument at other telescopes. The etalon delivers a resolving power in excess of 4000 (corresponding to a velocity resolution ∼75 km s-1), and allows imaging of fields up to 100″ in diameter on the AAT at any wavelength between 1.5 and 2.4 μm for which suitable blocking filters are available.
