Abstract: The mid-infrared interferometric instrument (MIDI) is planned to become operative at the ESO Very Large Telescope Interferometer (VLTI) in the year 2001. As for any other interferometers, many effects contribute to reduce the fringe visibility of MIDI, and eventually to affect its scientific capabilities. We present a preliminary visibility budget for MIDI: this is currently used to provide requirements for the optical design and in the definition of the scientific performances of the instrument. The role of atmospheric and diffraction effects for interferometry at mid-infrared wavelengths is also discussed. Finally an overview of the scientific objectives of MIDI is presented.
