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 ...

The limit of resolution of the transmission electron microscope is now less than 1 nm. The TEM has revealed structures in cells that are not visible with the light microscope.

In 1873, the German physicist Ernst Abbe realized that the resolution of optical imaging instruments, including telescopes and microscopes ... limit in achieving spatial resolution; using visible ...

The ingenuity and creativity of human researchers have led to the discovery of super-resolution (SR) methods, which overcome the classical diffraction limit of light at about 250 nm and enable one ...

Several approaches are capable of beating the classical 'diffraction limit'. In the optical ... with subwavelength resolution by using low-intensity light and without dependence on specific ...
