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 is worthwhile to contrast the diffraction of electrons with the diffraction of light by a two dimensional grid. It is also worthwhile to take along the model of the graphite crystal structure.

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

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 ...

Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could ...

Definition: X-Ray Diffraction (XRD) is a powerful analytical technique used to characterize the atomic and molecular structure of a crystal. By measuring the angles and intensities of diffracted beams ...
