Optical super-resolution resolves 137 nm features, matching SEM performance and exceeding a standard 100x objective.

In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...

At first glance, visible light and nanotechnology seem incompatible because of the diffraction limit, which dictates that features smaller than about half the wavelength of light cannot be resolved ...

The X-ray diffraction defined by Bragg's law is the sum total of diffraction patterns from molecules that strictly occupy the positions of a crystal's lattice units. Obtaining such a strictly ordered ...

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 ...

Physicists at The City College of New York have developed a technique with the potential to enhance optical data storage capacity in diamonds. This is possible by multiplexing the storage in the ...

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 ...

Abstract: The current fundamental limits such as Shockley–Queisser, ergodic light-trapping limit, diffraction-limited imaging (Abbe diffraction limit), noise in detection, reciprocal optical systems ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...
