Here’s a great picture from [Jelly & Marshmallows] that shows off the wild effects of melted chocolate poured onto a diffraction grating. A diffraction grating is a kind of optical component whose ...

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 ...

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 ...

A device that breaks up an electromagnetic wave into its different frequencies (wavelengths) by scattering them at different angles. For example, a series of thousands of scored lines in a glass plate ...

Editor's Note: To view a PDF version of the article, Click Here. The commercial introduction of wafer-based, nanofabrication techniques now makes it possible to create a new class of optical ...

Diffraction gratings create beautiful rainbow patterns when interacting with natural white light, and [audreyobscura] was familiar with their properties. Thus, she set about producing an attractive 3D ...

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 ...
