Three near infrared Y,J, and H broadband filters(MPIA) are mounted on a dedicated rotating wheel (IFAE, IEEC,ICE-CSIC & CEA/Irfu).The NISP Optical Assembly (built by MPE) made of a Correction Lens and a 3-lens focusing optics.A silicon carbide structure, developed by LAM,with elements provided by UiO, supporting the different NISP subsystems and interfacing with the Euclid Payload module.The NISP Opto-Mechanical Assembly (cooled to 130K) made of: The NISP instrument consists of three main assemblies: NISP was designed, built and tested under the lead of the Laboratoire d’Astrophysique de Marseille (LAM, France). We are looking forward to seeing the first light in flight demonstrating the excellent performances of the instrument.” Many major activities have to be completed with NISP at satellite level. However not the end of the story for the NISP team. Thierry Maciaszek (CNES/LAM), NISP instrument project manager, said, “The international NISP team in the Euclid Consortium and industries has made an incredible quasi perfect job to design, develop and test this challenging complex instrument. NISP is composed of several subsystems that were designed, built, and tested by a team of astronomers and engineers from several laboratories of the Euclid Consortium with the help and supports from the Centre National d’Etudes Spatial (CNES, France), the Astronomy and Particle Physics Departments of the Centre National de la Recherche Scientifique (CNRS, France),the Institute for Research on the Fundamental laws of the Universe (IRFU) Research Division of the Commissariat à l’Energie Atomique (CEA, France), the Agenzia Spaziale Italiana (ASI, Italy), the Istituto Nazionale Astrofisica (INAF, Italy), the Istituto Nazionale di Fisica Nucleare (INFN, Italy), the Deutsches Zentrum für LuftundRaumfahrt (DLR, Germany), the Max-Planck-Institut für Extraterestrische Physik (MPE, Germany), the Max-Plank-Institut für Astronomie (MPIA, Germany), the Ministerio de Economia y Competividad (MINECO, Spain), the Insitut de Física d’Altes Energies - The Barcelona Institute of Science and Technology (IFAE-BIST, Spain) and the Instittut d’Estudis Espacials de Catalunya - Institut of Space Science (IEEC-ICE-CSIC, Spain), Universidad Politecnica de Cartagena (Spain), the University of Oslo (UiO, Norway), the Norwegian Space Agency (Norway), the Niels Bohr institute (Denmark), the technical University of Denmark (DTU, Denmark), and NASA / JPL (USA).

It will collect light from distant cosmic objects and feed it into NISP and the second instrument, the VISible instrument (VIS), both working in parallel and observing the exact same regions of the sky at each exposure of the telescope.Įuclid will survey the 3-D distribution of galaxies and dark matter and map the geometry of the Universe with the aim of making accurate measurements of the mysterious Dark Matter and Dark Energy, which make up most of the cosmos. Once Euclid is launched from French Guiana in 2022, the NISP instrument will feed the world largest near infrared wide field camera put into space and will deliver near-infrared photometry, spectra and redshifts of tens of million distant galaxies providing a detailed description of the 3-dimensional structure of the universe, and its evolution as function of look back time.Įuclid has a 1.2-metre mirror telescope that is designed to work at both visible and near- infrared wavelengths. ESA’s Euclid mission to study more than a billion galaxies is a step closer to launch as its two instruments are now built and fully tested, including the complex near Near-Infrared Spectrometer and Photometer (NISP) instrument delivered by an international consortium coordinated by France, with partners from Italy, Germany, Spain, Denmark, Norway and the United States.
