Diffraction gratings are beautiful things, bending transmitted and reflected light and splitting it into its component wavelengths to create attractive iridescent rainbow patterns. It’s the same ...

Resonant effects in dielectric gratings were first clearly identified in the early 1990s 1 as having promise for applications in free-space optical filtering 2,3 and sensing 4,5. They typically occur ...

Guiding lasers where they need to go is a key part of optics systems, and now engineers at DESY have developed a way to bend laser beams without anything touching them. The light is deflected using an ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

Grating cheese on food is one of life’s ultimate pleasures. Shaving curls of salty dairy snow onto greens, soups, and pastas is coded into the food DNA of multiple cultures. Not to be an ...

Whether you get it off the block or grab handfuls from a bag, grated cheese is an important food. The tiny teeth of the grater transform it from a solid state into fluffy clouds of parmesan or piles ...

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 ...
