A variety of ultrathin nanomechanical diffraction gratings that have been fashioned from the “wonder material” graphene have been created by an international team of researchers. The team wanted to ...
Researchers at ETH Zurich have developed a method for the production of wavy surfaces with nanometer precision. In the future this method could be used, for instance, to make optical components for ...
Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...
WASHINGTON — Researchers have developed a process to turn crab shells into a bioplastic that can be used to make optical components known as diffraction gratings. The resulting lightweight, ...
Inprentus awarded contract to make convex gratings for TASA CubeSat-based greenhouse gas observatory
Inprentus won a TASA contract to produce diffraction gratings, closely following a recent NASA award, highlighting Inprentus’ growing role in space instruments. The contracts from NASA and TASA are ...
FROM an article in No. 2, vol. xxii., of the Astro-physical Journal, we learn that Mr. R. J. Wallace, of the Yerkes Observatory, has attained great perfection in the production of replicas from plane ...
Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...
