In 1873, the German physicist Ernst Abbe realized that the resolution of optical imaging instruments, including telescopes and microscopes, is fundamentally limited by the diffraction of light.

It predicts that electrons should show diffraction effects with crystals ... for example, a fluorescent screen or photographic plate, be placed in this space, the distribution of electrons ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...
