A Multi-Conjugate Adaptive Optics (MCAO) system is nearing completion at Gemini South.

By compensating for the atmospheric turbulence in a 3-D fashion, MCAO provides uniform image quality (diffraction-limited in the near-IR over a much wider field than regular AO (one to two arcmin in diameter depending on the IQ criterion).

More web pages for the MCAO will be created as system engineering and commissioning progresses. For now, please see the pages below or the Gemini adaptive optics pages for more details about Gemini's AO program in general.
