Abstract

Direct detection and spectral characterisation of extrasolar planets is one of the most exciting but also one of the most challenging areas in modern astronomy. For its second-generation instrumentation on the VLT, ESO has supported two phase A studies for a so-called ‘Planet Finder' dedicated instrument. Based on the results of these two studies, a unique instrument, SPHERE, is now considered for first light in 2010, including a powerful extreme adaptive optics system (SAXO), various coronagraphs, an infrared differential imaging camera (IRDIS), an infrared integral field spectrograph (IFS) and a visible differential polarimeter (ZIMPOL).
