The Planetary Systems Imager adaptive optics system: an initial optical design and performance analysis tool for the PSI-Red AO system

The Planetary Systems Imager (PSI) is a proposed instrument for the Thirty Meter Telescope (TMT) that provides an extreme adaptive optics (AO) correction to a multi-wavelength instrument suite optimized for high contrast science. PSI's broad range of capabilities, spanning imaging, polarimetry, integral field spectroscopy, and high resolution spectroscopy from 0.6–5 μm, with a potential channel at 10 μm, will enable breakthrough science in the areas of exoplanet formation and evolution. Here, we present a preliminary optical design and performance analysis of the 2–5 μm component of the PSI AO system, which must deliver the wavefront quality necessary to support infrared high contrast science cases.
