Indigo™ triangular glass prisms for white light dispersion and retroreflection.
Use for science lab demonstrations experiments or unique custom imprinted promotional gift items.
Understanding the visible light portion of the electromagnetic spectrum is a fundamental requirement of the basic sciences. This applies to physics & the spectroscopic analysis of stars, chemical reactions & the biology of photosynthesis & vision.
Sir Isaac Newton first demonstrated the dispersion of sunlight into the familiar rainbow component colors of violet, blue, green, yellow, orange and red using a triangular/equilateral glass prism. Glass prisms are better suited than acrylic prisms for experiments because of their higher refractive index for shorter wavelength blue light to longer wavelength red light.

Check out this chandelier made with special 225mm (9") equilateral glass prisms. The variety of different incident light angles makes for a stunning entrance. Thanks to Fabray Lighting Design, Comstock Design, TableM, and AdLight for sharing this image & allowing us to show it.
In addition to prisms, a glass stirring rod can demonstrate how refractive index influences the path of a light ray as it moves from one medium, air, to another, water.
