We report on the development and testing of the adaptive optics system for the 6.5 m single-mirror telescope that replaces the Multiple Mirror Telescope (MMT). This system features an adaptive secondary mirror and other innovations intended to give diffraction-limited infrared imaging with full sky coverage and the ultimate in low optical losses and thermal emissivity. In this paper, we first describe the system from a global perspective and then dwell particularly on the optical features of the system, the science package with integral tip/tilt guiding, and the solid-state sodium guide star laser. Other papers in this conference describe in more detail the innovative 300-actuator adaptive secondary, the control processor architecture and performance, and results from Fasttrac II, the immediate precursor to this system.
