Euclid is ESA's space mission to explore the dark Universe, launched on July 1, 2023. The VIS instrument is one of the two instruments on Euclid. It is a large format imager, with 609 million pixels covering a field of view of 0.57 deg2 (almost 3 times the solid angle of the full Moon) with 0.1 arcsec sampling. The VIS instrument is required to take sharp images in a broad optical filter for use in the weak lensing analysis, part of the core dark energy science from Euclid.
