Researchers have developed a graded grating structure that can be scaled to dimensions compatible with light waves in both the terahertz and telecommunications portion of the spectrum. The achievement ...

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 ...

Editor's Note: To view a PDF version of the article, Click Here. The commercial introduction of wafer-based, nanofabrication techniques now makes it possible to create a new class of optical ...

We build industry-leading instruments with our gratings, and you can too. Our transmissive VPH gratings offer the optical designer many advantages. They are more efficient and have much less scatter ...

Floor grating is frequently utilized where flooring is subject to extreme corrosion or in place of flat surfaces for industrial applications. It is most commonly associated with raised catwalks and ...

People debating politics are well-advised to shed more light than heat. Engineers working in optical technologies have the same aspiration. Light waves transmit data with much greater speed than do ...

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 ...
