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 effect you see on …read more Continue reading How To Get Your Diffraction Grating 3D Prints Right The First Time
[The Action Lab] had a very serious technical problem. His daughter wanted to 3D print sparkly unicorns. But how do you make a 3D print sparkly? Turns out, he had …read more Continue reading 3D Printing Rainbows
A monochromator is an optical instrument that permits only a narrow selection of wavelengths to be transmitted from a source, and the particular model [Doug] obtained renders visual light monochromatic …read more Continue reading Vintage Monochromator Makes Monochromatic Light, Mechanically
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 …read more Continue reading Iridescent Rainbow Chocolate, Just Add Diffraction Grating!
The 1960s were, in Western culture, a time of great social and political upheaval, and the dawning of the psychedelia subculture. This resulted in an art style consisting of bright colours in wild, shifting designs. [Afraser-kruck] has built a device capable of generating beautiful rainbow light patterns, which he calls …read more
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. This ability gives them all manner of important applications in the field of optics, but they’re also fun to play with. [Tech Ingredients] has done the hard work to find out how to make them out of candy!
The video starts with a basic discussion on the principles of diffraction gratings. The basis of the work is a commonly available diffraction grating, readily available online. It’s a plastic …read more
