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 ...

A: The resolution of an instrument that uses light to see things can’t improve beyond a point. This is called the diffraction limit. The resolving ability of, say, a telescope says how well it can ...

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 ...

A new microscopy technique significantly increases imaging resolution far beyond classical optics The new microscopy technique developed by the Japanese research team, led by Osaka University’s ...

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 ...

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 ...

What is Single-Molecule Localization Microscopy? Single-molecule localization microscopy (SMLM) is a super-resolution imaging technique that enables the visualization of biological structures and ...
