Abstract

The ENIS wide-field spectrograph is part of the instrument package on board of the European space mission Euclid devoted to map the dark universe and proposed for launch in 2017. ENIS will operate in the near-IR spectral region (0.8-2 μm) and will provide in 4-5 years an accurate and extremely large survey of cosmological redshifts. The instrument focal-plane is based on a combination of state of the art detectors light fed by a slitless spectrograph allowing coverage and analysis of a high number of targets per cycle. During the feasibility study a spectrograph option based on Digital Micromirror Device (DMD) programmable slits, allowing a significant increase in instrumental sensitivity and accuracy, has also been examined. ENIS has been recently (Feb this year) pre-selected for a phase-A study within a group of three medium class missions; final selection is foreseen for the end of next year after a new phase of instrument revision. A description of the work done during the feasibility-study phase for the ENIS focal-plane is here presented.
