The emergence of imaging schemes capable of overcoming Abbe's diffraction barrier is revolutionizing ... is fundamentally limited by the diffraction of light. His finding indicated that ultimately ...

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 ...

This may seem obvious but what happens on the far side of the gap or barrier is not so straightforward. The waves always 'spread' to some extent into the area beyond the gap. This is diffraction ...

It’s long been thought impossible for even the best optical microscopes to magnify objects any smaller than 200 nm for viewing, due to the natural diffraction of light. But scientists from Bangor ...
