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 ...

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 ...

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 ...

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 ...
