Paper Abstract

Euclid-VIS is a large format visible imager under investigation for the ESA Euclid space mission in their Cosmic Vision program. Together with the near infrared photometer (NIP) it forms the basis of the weak lensing measurements of Euclid. VIS will image in a single r+i+z band from 550-920 nm over a field of view of ~0.5 deg2. Over 4 exposures totalling 1800 sec, VIS will reach to V=24.9 (10σ) for sources with extent ~0.3 arcsec. The image sampling is 0.1 arcsec. VIS will provide deep imaging with a tightly controlled and stable PSF over a wide surcey area of of 20000 deg2 to measure the cosmic shear from over 2 billion galaxies to high levels of accuracy, from which the cosmological parameters will be measured. In addition, VIS will also provide a legacy deep imaging dataset of unprecedented spatial resolution over the entire extra-Galactic sky. Here we will present the results of the study carried out by the Euclid Imaging Consortium during the Euclid Assessment Phase.
