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 ...

Innovative research by Antonio Ambrosio presents a new material and technique for temporal light control, driving progress in ...

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 ...

For thousands of years, thinkers argued about whether light is made ... enough to showcase this phenomenon. However, researchers haven’t been able to show the diffraction of atoms through ...

High-powered lasers have transformed the way researchers explore extreme physical phenomena, pushing the boundaries of ...

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 ...

Attosecond science, honored with the 2023 Nobel Prize in Physics, is transforming our understanding of how electrons move in ...

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 ...
