Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies.

THE attention given, in this laboratory and elsewhere, to the effects produced by passing a beam of Röntgen radiation through crystals suggested to me that it might be of interest to examine the image ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

Two become one: various diffraction patterns showing Rayleigh's criterion. (Credit: Wikimedia Commons/Spencer Blevin) Scientists have long believed that diffraction limits the minimum distance that ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

The (relatively) ancient art of crystallography has had a huge impact on modern science by showing us the location of atoms within a molecule. The structure of DNA (and how it acts as an information ...

A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in ...

Using ultrahigh-intensity x-ray beams can cause the intensity of diffraction patterns from samples to drop Figure 1: An x-ray diffraction pattern obtained from a sample of Martian soil. X-ray ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...

In the field of scanning electron microscopy (SEM), the electron backscatter diffraction (EBSD) method has developed into a robust tool for the crystallographic analysis of materials. Specifically, ...
