HERMES

(four-channel spectrograph on the Anglo-Australian Telescope)

HERMES is a 4-channel Visible Light and Infrared (IR) Spectrograph unveiled in 2014 on the 3.9-meter Anglo-Australian Telescope (AAT). It is used for the GALAH survey. Its four bands:

Blue 471.8-490.3nm
Green 564.9-587.3nm
Red 648.1-673.9nm
IR 759.0-789.0nm

The 1.2-meter Mercator Telescope also has a spectrograph called HERMES, for High-Efficiency and high-Resolution Mercator Echelle Spectrograph, which covers a similar range: 380nm through 875nm.
