A paper by Kazan Federal University's Sergey Kharintsev appeared in Optics Letters. The research was supported by a Russian Science Foundation's grant under the title "Synthesis and research of a new ...

Harnessing light's energy into nanoscale volumes requires novel engineering approaches to overcome a fundamental barrier known as the 'diffraction limit.' However, researchers have breached this ...

Researchers have developed a noninvasive technique that can capture images of rod and cone photoreceptors with unprecedented detail. The advance could lead to new treatments and earlier detection for ...

Nanoscopy is a field of microscopy that focuses on imaging and studying structures and processes at the nanoscale, typically below the diffraction limit of light. It encompasses various techniques ...

Researchers from the University of Science and Technology of China (USTC) led by Prof. ZHANG Douguo have unveiled a planar optical device that significantly enhances the capabilities of dark-field ...

Stimulated emission depletion (STED) microscopy has shown that diffraction-unlimited spatial resolution is viable with conventional lenses and visible light. Stefan W Hell, Lars Kastrup and Katrin I ...

The Abbe diffraction barrier, which fundamentally restricted the lateral optical resolution to 200 – 300 nm until the early 1990s, can be overcome by super-resolution optical fluorescence imaging ...
