Adaptive Optics (AO)

As members of the Center for Adaptive Optics (CfAO) we use the adaptive optics systems at the Lick and Keck observatories. Turbulence in our atmosphere limits the seeing of telecopes to approximately 1 arcsecond, while the diffraction limit of a telescope is approximately equal to the ratio of the wavelength and the diameter of the mirror.
