<i>Euclid</i>-VIS is the large format visible imager for the ESA <i>Euclid</i> space mission in their Cosmic Vision program, scheduled for launch in 2020. Together with the near infrared imaging within the NISP instrument, it forms the basis of the weak lensing measurements of <i>Euclid</i>. VIS will image in a single <i>r+i+z</i> band from 550-900 nm over a field of view of ~0.5 deg<sup>2</sup>. By combining 4 exposures with a total of 2260 sec, VIS will reach to deeper than mAB=24.5 (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 point spread function (PSF) over a wide survey area of 15000 deg<sup>2</sup> to measure the cosmic shear from nearly 1.5 billion galaxies to high levels of accuracy, from which the cosmological parameters will be measured. In addition, VIS will also provide a legacy dataset with an unprecedented combination of spatial resolution, depth and area covering most of the extra-Galactic sky. Here we will present the results of the study carried out by the <i>Euclid</i> Consortium during the period up to the Critical Design Review.
