Abstract

The optical vortex coronagraph is a promising scheme for achieving high contrast low loss imaging of exoplanets as close as 2λ/D from the parent star. We describe results using a high precision vortex lens that was fabricated using electron-beam lithography. We also report demonstrations of the coronagraph on a telescope employing a tip-tilt corrector.
