Within most microstructured fibres investigated until now, the light intensity at the air–glass boundaries is low relative to the peak intensity in the core, as the air holes are typically ...

The emergence of imaging schemes capable of overcoming Abbe's diffraction barrier is revolutionizing optical microscopy. In 1873, the German physicist Ernst Abbe realized that the resolution of ...

I’ve heard it said that, if February weren’t short, nobody would survive the winter. We go into this month with an expectation of impermanence, time here and gone quicker than ice floating down the ...

Description: Electron diffraction patterns for single crystal and polycrystalline materials are displayed on a CRT screen. A Welch model 2639 'Electron Diffraction tube' is used in an experiment in ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

Researchers from Oakland University have made a significant breakthrough in the field of optical materials, unveiling the ...
