Glass Equilateral Prisms

Designed for educational purposes and science classroom demonstrations in optics, light refraction, spectrometry, and wavelengths.

These glass prisms will create a nice rainbow (even in room light) by using the simple LED light of a smart phone. Users will need to create a small slit in a black piece of paper and use that slit in front of the LED, which will create a light ray. The prisms will then refract the white light and create a nice rainbow on a target away from the prism. The farther away you move the target, the bigger the rainbow gets and the more distinct colors the user can see.
