(spectrograph planned for E-ELT)
HARMONI
(for High Angular Resolution - Monolithic - Optical and Near-infrared - Integral Field Spectrograph)
is a planned visible-light/near-infrared spectrograph
with an integral field unit, intended to be one of the first instruments
installed on the European Extremely Large Telescope, i.e., a first-light instrument.
Spectral resolution over its wavelength-range will
vary from R~3000 to R~20000.
The IFU aims to handle thousands of targets.
The aim is that it serve as the widely-used, general-purpose spectrograph
(as opposed to more specialized instruments),
that it be easy to operate and that it work efficiently,
i.e., perform observations with minimal time overhead.
