“…It combines 4 fixed Unit Telescopes (UTs) with 8m diameter or 4 relocatable Auxiliary Telescopes with 1.8 m diameter. Its longest baseline is currently of 135 m and will soon be extended for ATs to the maximum value of 200 m allowed by the size of the platform at the top of mount Paranal [1]. The VLTI features two 2 nd generation instruments open the "General User", GRAVITY in the K band [2,3] and MATISSE in the mid infrared covering the L, M and N bands from 3 to 13 µm [4,5].…”

MATISSE, the VLTI 2 nd generation spectro-interferometric L, M and N bands imager, has been commissioned from March 2018 to March 2020. It is open to the General User since April 2019. A complete analysis of its performances is given in this paper for MATISSE standalone (with UTs and ATs) and for the GRAVITY for MATISSE (GRA4MAT) mode (with ATs) where the GRAVITY fringe tracker is used to stabilize the fringes in MATISSE and hence improve its sensitivity and spectral coverage at high spectral resolution. This paper presents the key operation parameters of MATISSE and decomposes its performances in fundamental precision per spectral channel for all measurements and in broad band calibration errors on the accuracy of visibility and closure phase. It is intended to give the user a full description of the different errors that must be considered and weighted in the model fitting and image reconstruction. The first image reconstructions achieved by MATISSE are discussed. The performances demonstrated here in the full very broad spectral domain of MATISSE open a very large domain of scientific applications that includes but strongly expands quantitatively and qualitatively the initial science program of the first generation instrument MIDI and, combined with GRAVITY, offers an extremely powerful tool to characterize the temperature and composition of dusty and molecular components of YSOs, AGNs and evolved stars.

Chromatic dispersion is a well-known technical challenge in optical interferometry, and the issue is exacerbated when using optical fibers for beam transport. The important sources of chromatic dispersion in a fiber-coupled optical interferometer are investigated using a Mach–Zehnder interferometer operating between 975–1650 nm, with particular attention paid to various dispersive effects in fibers. The compensation of chromatic dispersion is also investigated, and a compensation strategy using bulk glass and fiber stretching is described. A notional dispersion budget is presented for a fiber-coupled interferometer operating in the near infrared, showing that dispersion can be compensated to the λ / 20 RMS level over a nearly 700 nm wide bandpass.
