For thousands of years, thinkers argued about whether light is made of particles or waves. At the beginning of the 20th century, scientists realized it was both: massless particles and waves.

Sure, a hacker could make one if he or she put their mind to it. But make one out of a webcam, some cheap diffraction grating purchased off ebay and some scrap? Surely not. [Renaud] pulls off this ...

The story begins several decades ago, in 1927, when physicist George Paget Thomson revealed that electrons, when passed through a crystal grating, produce a diffraction pattern—a hallmark of ...

The solution was then cast on a holographic diffraction-grating master mould to obtain free-standing silk gratings with a grating pitch of 600 grooves per millimetre, as shown in Fig. 4.

Coherent (COHR) announced the launch of its Ultrabroadband UV-VIS and VIS-NIR Diffraction Gratings. The company said, “These cutting-edge ...
