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 ...

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 ...

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 ...

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 ...

At Holographix, we design and manufacture cost-effective, high performance replicated custom diffraction gratings to customer specifications. We produce a wide range of custom solutions, including ...

On Wednesday the 25th of May 2022, M.Sc. (Tech) Mikko Toivonen defends his doctoral thesis on Practical Spectral Diffraction Imaging. The thesis is related to research done in the Department of ...
