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 ...

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 ...

Researchers in Switzerland have made a popular materials characterization technique accessible to ultrafast X-ray laser light for the first time. The new approach allowed the team to film atomic ...

Holographic and Ruled diffraction gratings are available from Optometrics for use in high-level spectroscopy, alongside our Echelle, Filtered and Transmission gratings. One of the few gratings ...

The research team of the State Key Laboratory of Precision Spectroscopy at East China Normal University has made significant progress in the field of ultra-fast laser-induced breakdown spectroscopy ...

There was a question from Jerry in a previous post: "A simple question for which I can't find an answer: Why do you have to collimate light spectroscopy? What would happen if you didn't collimate it?" ...

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 ...
