Abstract

The Magellan Adaptive Optics system (MagAO) saw first light in November 2012 at Las Campanas Observatory on the 6.5m Clay telescope. Here we present an introduction to MagAO's visible wavelength diffraction limited imager, VisAO. VisAO delivers Strehl ratios greater than 30% from 0.62 microns (r') through 1 micron, where Strehl is even higher, and achieved resolutions as small as 20 milli-arcseconds. There are several design considerations which allow VisAO to achieve such good performance on a large telescope, and these will have important implications for ELT AO systems. We took advantage of the excellent performance of MagAO/VisAO to conduct high contrast observations of an exoplanet in the optical.
