Final design details are given for UnISIS, the University of Illinois Seeing Improvement System. The principle components include a 50 Watt Excimer laser working at 351 nm which produces a pulsed Rayleigh laser guide star at 333 Hz and 18 km altitude, a 177-actuator deformable mirror, an atmospheric dispersion correction system, and a science camera configuration with both visual and near-IR cameras that can be used simultaneously. Two high-speed CCD cameras are used to feed dual quad C40 DSP-based reconstructor to close the feedback loop with the deformable mirror. The adaptive optics system is situated on a large optics table that rests above the old Coude spectrograph of the Mt. Wilson 2.5-m telescope and the Excimer laser is located in a basement Coude room.
