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, inexpensive gratings ...

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 ...

Diffraction gratings are curious things. Score a series of equally spaced tiny lines in a surface, and it will cause reflected or transmitted light to bend and separate into its component wavelengths.

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 new approach could enable kilometer length telescope membranes to be launched with current rockets for radically improved space telescopes. In a presentation to the NASA Institute for Advanced ...

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, ...

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 ...

McPherson's SXR spectrometer, Model 251MX, is now available with improved efficiency over a wider range. A new diffraction grating is available! The new Gold coated diffraction grating is ideal for ...

Sunlight reaches the earth as white light, which is made up of all the rainbow colors. Rainbow colors are red, orange, yellow, green, blue, indigo, and violet. It is easy to remember them by using the ...
