Design update of the laser guide star system for NFIRAOS using the C-Blue One camera

NFIRAOS is the first-light adaptive optics system for the Thirty Meter Telescope (TMT). It features a laser guide star wavefront sensor system, which helps to correct atmospheric distortion over a 2 arc-minute field of view. Since the final design review for NFIRAOS in 2018, a trade-study was undertaken to consider a new camera from First Light Imaging called C-Blue One as the LGS wavefront sensor. A redesign of the LGS subsystem of NFIRAOS was undertaken to incorporate this new wavefront sensor into the design with updated AO tolerances, optics, and a new relay system to reimage a high density lenslet-array onto the small sensor.
