It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

Researchers from the University of Science and Technology of China (USTC) have unveiled a planar optical device that significantly enhances the capabilities of dark-field microscopy, achieving ...

For hundreds of years, the optical microscope was the only tool available to scientists wanting to study the movement of cells, bacteria and yeast. But the diffraction of light made it impossible to ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...

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 ...

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 ...

Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies. (Nanowerk News) Physics is full of pesky ...

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 ...
