The Planetary Systems Imager (PSI) is a proposed instrument for the ThirtyMeter Telescope (TMT) that provides an extreme adaptive optics (AO) correctionto a multi-wavelength instrument suite optimized for high contrast science.PSI's broad range of capabilities, spanning imaging, polarimetry, integralfield spectroscopy, and high resolution spectroscopy from 0.6-5 microns, with apotential channel at 10 microns, will enable breakthrough science in the areasof exoplanet formation and evolution. Here, we present a preliminary opticaldesign and performance analysis toolset for the 2-5 microns component of thePSI AO system, which must deliver the wavefront quality necessary to supportinfrared high contrast science cases. PSI-AO is a two-stage system, with aninitial deformable mirror and infrared wavefront sensor providing a commonwavefront correction to all PSI science instruments followed by a dichroic thatseparates "PSI-Red" (2-5 microns) from "PSI-Blue" (0.5-1.8 microns). To meetthe demands of visible-wavelength high contrast science, the PSI-Blue arm willinclude a second deformable mirror and a visible-wavelength wavefront sensor.In addition to an initial optical design of the PSI-Red AO system, we present apreliminary set of tools for an end-to-end AO simulation that in future workwill be used to demonstrate the planet-to-star contrast ratios achievable withPSI-Red.
