HARMONI (High Angular Resolution - Monolithic - Optical and Near-infrared - Integral field spectrograph) is one of the first-light instrument for the ESO-European Extremely Large Telescope.

Harmoni timeline


HARMONI is an integral field spectrograph operating at the visible and near-infrared spectral range (0.5–2.4 µm), with mid (R=4000) and high spectral resolution (R=20000), covering a low fiel of view (1-10 arcsec) with a spatial sampling between 4 and 40 milliarcsec and providing 30 000 spectra per exposure .

HARMONI is designed with the use of different adaptive optics systems (SCAO, GLAO and LTAO). With such a characteristics, HARMONI for the E-ELT represents the equivalent of SIFONI for the VLT. HARMONI will benefit from a spectacular gain with the collecting power of a 39 m telescope and high spatial resolution which will make possible a deep observation of astrophysical objects such as, for example, the active noyaux of galaxies, the supermassive black-holes supermassifs up to z=2 and galaxies (primordiales) with z>7.

Harmoni optomechanical design


The LAM/ONERA team has the responsibility of the SCAO and LTAO (up to PDR) modules for HARMONI. The High-Contrast module, although driven by its collaborators at IPAG, is also under LAM responsibility.

Harmoni is a consortium gathering 10 european institutes (from United Kingdom, France and Spain) working in collaboration with ESO.
