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 ...

A laser beam is shone onto a variable rectangular aperture. The size of the hole determines the type of diffraction produces on the screen. Very small apertures produce Fraunhofer diffraction, and ...

When a laser beam is incident on many small objects such as lycopodium powder, the resulting diffraction pattern is similar to the diffraction pattern of a small circular aperture (Airy's disk pattern ...

Using ultrahigh-intensity x-ray beams can cause the intensity of diffraction patterns from samples to drop Figure 1: An x-ray diffraction pattern obtained from a sample of Martian soil. X-ray ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...
