Extremely Large Telecope (ELT)

The ELT is a project led by ESO (European Southern Observatory) aimed at building a 40m optical/near-infrared telescope. It will be the largest telescope in the world and will gather 13 times more light than the largest optical telescopes existing today. The ELT will be able to correct for the atmospheric distortions (i.e., fully adaptive and diffraction-limited) from the start, providing images 16 times sharper than those from the Hubble Space Telescope.

We participate in HARMONI, the 1st light spectrograph for ELT.  It is an optical and near-infrared integral field spectrograph, able to record simultaneously ~32000 spectra over a two-dimensional region, at the diffraction limit of the telescope.  We are members of the HARMONI consortium, which is led by the University of Oxford and it is also formed by UK-ATC-Edinburgh, CRAL-Lyon, IAC-Tenerife, LAM-Marseille. The project has now started its development phase, and the CAB is responsible of two subsystems (calibration, and secondary guiding). It also contributes in the scientific oversight during the development phase, and will also participate in the first scientific programs to be carried out with the instrument.
