E-ELT Multi-Conjugate Adaptive Optics module: image quality performance
Abstract
The Multi-conjugate Adaptive Optics RelaY (MAORY) for the European Extremely Large Telescope (E-ELT) provides a corrected field of view of up to 2 arcmin diameter over the wavelength range 0.8-2.4 micron. It is expected to achieve a correction of high quality and uniformity with high sky coverage: with a seeing of 0.8 arcsec in the visible, the expected Strehl Ratio averaged over a 1 arcmin field is approximately 50% at 2.16 micron wavelength over 50% of the sky at the Galactic Pole. This paper describes the module design and expected image quality performance. The results presented here are based on the MAORY phase-A study that was completed in late 2009. At the moment of this writing the Consortium and the management plan for the next phases of the instrument construction are in preparation.
