MATISSE (Multi-AperTure mid-Infrared SpectroScopic Experiment) is a mid-infrared spectro-interferometer project combining up to four UTs/ATs beams of the VLTI. It will measure closure phase relations, thus offering an efficient capability for image reconstruction. This mid-infrared instrument will include several efficient spectroscopic modes.

On the left menu you will be able to browse information on the consortium, the instrument, the science goals.
