Abstract

The ESA/EUCLID satellite is equipped with two instruments that are simultaneously observing patches of < 0:5 square degree on the sky. The VIS visual light high spacial resolution imager and the NISP near infrared spectrometer and photometer are separated by a di-chroic beam splitter. The huge field of view, together with the enormous demands on the optical performance and in flight stability of the instruments and telescope lead to unique demands in post launch alignment. A very detailed, very well set up optical tolerance analysis is therefore one key point in the success of the mission. Design and alignment have to be optimized for best toleranced performance. This paper presents the baseline concept of the NISP instrument with its two observational modes being low resolution slit-less spectroscopy and three band J, H&K+ photometry. Special chapters deal with the alignment scheme and the derived tolerance approach which will be used towards the instrument PDR.
