Diffraction Limited

(telescope limited only by the laws of diffraction)

A Diffraction Limited telescope, microscope or camera is such an instrument designed so that its resolution limit is based upon Diffraction rather than Atmospheric conditions or construction flaws of the equipment.

Alternately, a telescope can be Seeing Limited, i.e., limited by atmospheric conditions. Locating a telescope in space or using Adaptive Optics are means of removing the seeing limits.
