A wide selection of broad-band and narrow-band filters is available, and can be shared between AAO instruments.
All detectors are now operated with the AAO-2 controllers. The MITLL3 and EEV2 CCD pages give details on the performance of these detectors with UCLES and UHRF with the old controllers. See the CCD Performance with the AAO-2 Controllers page for latest details on performance of the EEV2 and MITLL3 detectors on UCLES/UHRF.
Current AAT Instruments
- AAOmega fibre-fed optical spectrograph, fed by either:
- HERMES - fibre-fed four-channel high-resolution spectrograph, fed by the 2 Degree Field (2dF) robotic fibre positioner covering a 2 degree field at prime focus with 392 fibres. HERMES commissioning was carried out in Semester 13B. The instrument is overall behaving as expected, though detailed commissioning results are not yet available.
- IRIS2 - 1.0-2.5 micron infrared imager and longslit/multi-slit spectrograph covering a 7.7' x 7.7' field.
- University College London Echelle Spectrograph (UCLES) - cross-dispersed echelle spectrograph with resolution R = 40,000 - 120,000. Can also be used with the CYCLOPS2 fibre-feed with the 79 l/mm echelle.
- Ultra High Resolution Facility (UHRF) - echelle spectrograph with R = 300,000, 600,000, or 940,000.
- Visitor Instruments may be used on the AAT with permission from the Director. Please see these pages for more information.
