The NISP (Near Infrared Spectrometer and Photometer) is one of the two Euclid instruments (see ref [1]). It operates in the near-IR spectral region (950 -2020nm) as a photometer and spectrometer. The instrument is composed of: - a cold (135 K) optomechanical subsystem consisting of a Silicon carbide structure, an optical assembly, a filter wheel mechanism, a grism wheel mechanism, a calibration unit, and a thermal control system,
- a detection system based on a mosaic of 16 H2RG with their front-end readout electronic, and
- a warm electronic system (290 K) composed of a data processing / detector control unit and of an instrument control unit that interfaces with the spacecraft via a 1553 bus for command and control and via Spacewire links for science data.
This paper presents:
- the final architecture of the flight model instrument and subsystems, and
- the performance and the ground calibration measurement done at NISP level and at Euclid Payload Module level at operational cold temperature.
