Microscopes have long been scientists’ eyes into the unseen, revealing everything from bustling cells to viruses and nanoscale structures. However, even the most powerful optical microscopes have been ...

Introduction to SNOM: The Scanning Near-field Optical Microscope (SNOM) stands as a pivotal analytical tool in nanotechnology, enabling the visualization of nanostructures with resolution beyond the ...

Researchers at Tsinghua University developed the Optical Feature Extraction Engine (OFE2), an optical engine that processes data at 12.5 GHz using light rather than electricity. Its integrated ...

Raman microscopy combines optical microscopy with the ability to determine the chemical makeup of surfaces. Laser light is delivered to the sample surface via the same objective as the optical light ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

Advanced light microscopy techniques are giving scientists a new understanding of human biology and what goes wrong in diseases Katarina Zimmer, Knowable Magazine Innovative techniques are helping ...

Computational fluorescence microscopy (CFM) requires accurate point spread function (PSF) characterization for high-quality ...

If you think of a single atom as a grain of sand, then a wavelength of visible light—which is a thousand times larger than the atom's width—is comparable to an ocean wave. The light wave can dwarf an ...

Using a tiny, spherical glass lens sandwiched between two brass plates, the 17th-century Dutch microscopist Antonie van Leeuwenhoek was the first to officially describe red blood cells and sperm cells ...
