Microscopy uses radiation and optics to obtain a magnified image of an object. The resolution of the imaging is limited by the minimum focus of the radiation due to diffraction. For light microscopy the diffraction limit is approximately 1 um (10-6 m) and for high-resolution electron microscopy the limit is approximately 1 Å (10-10 m).
