HARMONI

(High Angular Resolution - Monolithic - Optical and Near-infrared - Integral field spectrograph, ELT-HARMONI, ELT-IFU)
(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~17000. 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.
