Abstract (EN): NIRPS, the Near Infra-Red Planet Searcher, is part of a new generation of Adaptive Optics fibre-fed spectrographs. It will be installed in the ESO La Silla 3.6 m telescope and will be operated individually or jointly with HARPS. NIRPS aims at spectroscopic observations of stellar objects in the NIR, from 970 nm to 1800 nm (with the option for later extension to 2400 nm). The instrument is assisted by an AO system, whose sensing bandwidth will be from 700 nm to 950 nm. Even if telescope pointing and guiding is perfect at a given reference wavelength, atmospheric dispersion will shift the image centroid at different wavelengths, with impact on fibre injection. Moreover such effect will vary during acquisition with the observation zenith angle. Therefore an Atmospheric Dispersion Corrector (ADC) is mandatory to achieve the instrument requirements. In this paper we will present the design, integration and test results for the NIRPS ADC.
