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 ...

Physicists from MIPT and University Jean Monnet (France) have developed a new simulation method for optical elements used in many modern instruments and devices. Their paper, presenting a description ...

Researchers have developed a new technique that enables sensitive and specific detection of molecules at the electrode/electrolyte interface. This new method uses diffraction from graphene gratings to ...

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 ...

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 ...

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 ...
