HARMONI is a first light optical / infrared spectrograph of integral field and high spatial resolution for ELT. Its design and construction is carried out by an international consortium in which the IAC participates together with the University of Oxford, ATC-Edinburgh, Durham University, CRAL-Lyon, LAM-Marseille, CSIC-CAB-Madrid, and the

Infrared high-resolution echelle spectrograph for the Great Telescope CANARIAS (GTC) of the Observatorio del Roque de los Muchachos in the island of La Palma. The main scientific objective of the instrument is to measure the radial velocity (RV) with very high precision (goal of 1 m/s) in the near infrared.
