By using deep learning to optimize the structures of a series of passive, isotropic diffractive layers, the team created a compact and broadband optical system that efficiently focuses light 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 ...

Several approaches are capable of beating the classical 'diffraction limit'. In the optical domain, not only are superlenses a promising choice: concepts such as super-oscillations could provide ...

Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering (IOF) say that they have built a thulium fiber laser capable of emitting 1.91 kW - nearly double the typical output ...

Specially made diffraction gratings use optical laser light to illustrate how wave-based material characterization techniques work, such as X-ray diffraction, electron diffraction, and neutron ...

In addition to the ability to make highly specialized large diffraction gratings, Inprentus has increasingly been sought after for higher volume production of ultra-precise smaller gratings. Compared ...

have unveiled a planar optical device that significantly enhances the capabilities of dark-field microscopy, achieving ...

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 ...
