000004381 520__ $$aThe Extreme Ultraviolet Imager (EUI) is part of the remote sensing instrument  package of the ESA/NASA Solar Orbiter mission that will explore the inner  heliosphere and observe the Sun from vantage points close to the Sun and out of  the ecliptic. Solar Orbiter will advance the `connection science' between solar  activity and the heliosphere. } With EUI we aim to improve our understanding of the structure and dynamics of  the solar atmosphere, globally  as well as at high resolution, and from high  solar latitude perspectives. The EUI consists of three telescopes, the Full Sun Imager (FSI) and two High  Resolution Imagers (HRIs), which are optimised to image in Lyman-$\alpha$ and  EUV (\SI{17.4}{\nano\metre}, \SI{30.4}{\nano\metre}) to provide a coverage  from chromosphere  up to corona. The EUI is designed to cope with the strong  constraints imposed by the Solar Orbiter mission characteristics. Limited  telemetry availability is compensated by state-of-the-art image compression,  onboard image processing, and event selection. The imposed power limitations  and potentially harsh radiation environment necessitate the use of novel CMOS  sensors. As the unobstructed field of view of the telescopes needs to protrude  through the spacecraft's heat shield, the apertures have been kept as small as  possible, without compromising optical performance. This led to a systematic  effort to optimise the throughput of every optical element and the reduction  of noise levels in the sensor. In this paper we review the design of the two elements of the EUI instrument:  the Optical Bench System and the Common Electronic Box. Particular attention  is also given to the onboard software, the intended operations, the ground  software, and the foreseen data products.} The EUI will bring unique science opportunities thanks to its specific design,  its viewpoint, and to the planned synergies with the other Solar Orbiter  instruments.  In particular, we highlight science opportunities brought by the   out-of-ecliptic vantage point of the solar poles, the high-resolution   imaging of the high chromosphere and corona, and the connection to the outer   corona as observed by coronagraphs.
