Capable of delivering diffraction limited images in the near-infrared, over an 85''x85'' square field-of-view, GSAOI was designed for use with the Gemini Multi-Conjugate Adaptive Optics (GeMS) system in operation at the Gemini South Observatory. The instrument focal plane, covered by an array of four HAWAII-2RG detectors, contains 4080x4080 pixels and has a plate scale of 0.02'' - thus capitalizing on the superb image quality delivered by both the all-refractive optical design of GSAOI and the Gemini South MCAO system. Here, we discuss our preliminary findings from the GSAOI commissioning, concentrating on detector characterization, on-sky performance and system throughput. Further specifics about the Gemini MCAO system can be found in other presentations at this conference.Author/s retain copyrightKeywords: Adaptive optics systems; Gemini; Image; Instrument commissioning; Instrumentation; Near Infrared; Buildings; Infrared devices; Instruments; Observatories; Optical design; Adaptive optics Adaptive optics system; Gemini; Image; Instrument commissioning; Instrumentation; Near-infrared201210.1117/12.9262402016-02-24
