NFIRAOS is an MCAO system for the Thirty Meter Telescope, serving 3 client scientific instruments. It has 2 deformable mirrors, 6 laser wavefront sensors, and uses up to 3 low-order (tip/tilt and/or focus) IR wavefront sensors (OIWFS) on each instrument and up to 4 guide windows on the client’s science detector to correct atmospheric turbulence, windshake, optical errors and plate scale distortion. NFIRAOS’ Intel Xeon-based real time computer is approaching final design review. This facility Adaptive Optics system for the TMT is cooled to -30 C. NFIRAOS is under final design at NRC Herzberg in Victoria Canada, and at industrial partners in Canada.
