where λ is the wavelength of light and NA is the numerical aperture of the imaging lens. This diffraction-limited phenomenon hindered the performance of optical microscopy for over a century ...

The first reference to diffraction phenomena appears in the work of Leonardo da Vinci (1452–1519). Such phenomena were, however, first accurately described by Grimaldi in a book, published in 1665, ...

For over a century, science has relentlessly pursued the demonstration of atom diffraction, a critical phenomenon for ...

For thousands of years, thinkers argued about whether light is made of particles or waves. At the beginning of the 20th ...

Diffraction happens when light waves encounter obstacles, such as water droplets, causing the light to bend and spread out. The droplets responsible for this phenomenon are usually much smaller ...

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 ...

It leverages phenomena like plasmonics, near-field optics, and quantum optics to manipulate light at the nanoscale, overcoming the diffraction limit that restricts the focusing of light in ...
