Aims. This paper describes the design goals and engineering efforts that led to the realization of AMBER (Astronomical Multi BEam combineR)
and to the achievement of its present performance.
Methods. On the basis of the general instrumental concept, AMBER was decomposed into modules whose functions and detailed characteristics
are given. Emphasis is put on the spatial filtering system, a key element of the instrument. We established a budget for transmission and contrast
degradation through the different modules, and made the detailed optical design. The latter confirmed the overall performance of the instrument
and defined the exact implementation of the AMBER optics.
Results. The performance was assessed with laboratory measurements and commissionings at the VLTI, in terms of spectral coverage and resolution,
instrumental contrast higher than 0.80, minimum magnitude of 11 in K, absolute visibility accuracy of 1%, and differential phase stability
of 10−3 rad over one minute.
