C-BLUE One: a new CMOS camera dedicated for laser guide star wavefront sensing on ELTs

After releasing reference camera solutions in the visible and infrared for natural guide star wavefront sensing with unbeaten performances, we will present the first results of First Light Imaging’s C-BLUE One (formerly introduced under the name “C-MORE”), the first laser guide-star-oriented wavefront sensor camera. Within the Opticon WP2 european funded project which has been set to develop LGS cameras, fast path solutions based on existing sensors had to be explored to provide working-proven cameras to ELT projects ready for the first light schedule. Result of this study, C-BLUE One is a CMOS based camera with 1600x1100 pixels (9um pitch) and up to 660 FPS refresh rate. It has been developed to answer most of the needs of future laser based adaptive optics systems (LGS) to be deployed on 20-40m-class telescopes as well as on smaller ones.
