Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original ...

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 ...

One of the coolest things about physics is that the same basic concept can pop up in several seemingly unrelated things: say, a CD, the seed shrimp’s antennae, certain fossils in the Burgess shale, ...

The Inprentus Team has developed proprietary software to predict diffraction efficiency of real, manufactured groove shapes illuminated at designed scattering conditions, order, and energy range. The ...

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 ...

Here’s a great picture from [Jelly & Marshmallows] that shows off the wild effects of melted chocolate poured onto a diffraction grating. A diffraction grating is a kind of optical component whose ...

Reflective ruled diffraction grating is a kind of optical glass substrate composed of dense, equidistant parallel lines, and the surface is coated with aluminized, multi-layer dielectric or other ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Chocolate is already wonderful, but did you know that it can also ...

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, ...
