AAOmega, commissioned in 2006 and upgraded in 2014, is a general-purpose facility providing multi-object and integral field spectroscopy at the AAT. This dual beam bench mounted multiple-object spectrograph is fed by ~400 fibres from 2dF providing spectral resolutions ranging from 1,200 to 10,000 with a variety of VPH gratings.
The AAOmega spectrograph can be fed by several front-ends, either the Two Degree Field (“2dF”) multi-object system, the KOALA integral field unit, or the SAMI multi-IFU system.
