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 ...

There is always something interesting to find when browsing the projects on Hackaday.io. I’m always amazed at how much hackers can get done in their basements and home labs. One surprising trend I’ve ...

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.

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 ...

Imagine knowing what berry or mushroom is safe to eat during a hike or swiftly detecting pathogens in a hospital setting that would traditionally require days to identify. Identification and detection ...

The significance of the entrance slit and the diffraction grating in forming a spectral image of the incident light in the image plane is discussed in the articles “An Introduction to a Spectrometer: ...

Hamamatsu Photonics has introduced a UV model of its ‘micro’ spectrometer series. C16767MA is sensitive across 190 to 440nm with a typical resolution of 5.5nm (FWHM, so ±2.25nm to 50%). Update: scroll ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS In a study published in Light: Science & Applications, researchers from Diamond Light Source (United Kingdom), ...

Metasurface performance: A schematic diagram of the proposed metasurface spectrometer based on a wavelength dependent multi-foci metalens model. (Courtesy: Ruoxing Wang, Muhammad Afnan Ansari, Hammad ...

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 ...
