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

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 ...

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 ...

Test for echo: schematic diagram of an object to be imaged (blue blob) and illumination source (concentric circles) inside a randomly shaped cavity. The detector is represented by the two parallel ...

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 ...

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 ...

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 ...
