HERMES
(four-channel spectrograph on the Anglo-Australian Telescope)
HERMES is a 4-channel visible light and infrared
spectrograph unveiled in 2014 on the 3.9-meter Anglo-Australian Telescope.
It can operate as a multi-object spectrograph with
the telescope's robot fiber positioner.
It is used for astronomical surveys such as GALAH.
Its four bands:
| Blue | 471.5-490.0 nm |
| Green | 564.9-587.3 nm |
| Red | 6487.8673.7 nm |
| IR | 758.5-788.7 nm |
The name HERMES (for High-efficiency and High-resolution Mercator Echelle Spectrograph)
is also used for an unrelated spectrograph
on the 1.2-meter Mercator Telescope,
which covers a similar range: 380-875 nm.
