"SPHERE, the New High-contrast Imager for the ESO-VLT"

Direct imaging of planets is one of the major challenges for current astrophysics. SPHERE is the new high contrast imager for the ESO-VLT. SPHERE has been constructed by a consortium including institutes from five different European countries (France, Italy, Germany, Switzerland, and the Netherlands) and ESO, lead by Jean-Luc Beuzit (IPAG, France). SPHERE is a state-of-the-art instrument including a very powerful extreme adaptive optics system (SAXO), a common path providing very stable and accurately calibrated optical path, a suite of coronagraphs, and three scientific channels: IRDIS, a dual band imager which allows imaging, long slit spectroscopy and polarimetry in the near infrared; IFS, an integral field spectrograph, still for near infrared; and ZIMPOL, the image-polarimeter for visible wavelengths. SPHERE has been commissioned during 2014, achieving 5-sigma contrast limits better than 10-6 at 0.5 arcsec from the central star in favourable cases. I will present the principles behind this very performing instrument and some early results.
