HERMES

HERMES (for High Efficiency and Resolution Multi-Element Spectrograph) 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 robotic fiber positioner (2dF). It is used for astronomical surveys such as GALAH. Its four bands:

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.
