Prisms & Colour
Buy optical prisms & make rainbows colour your walls & your life. Make beautiful rainbow spectra with our prisms and diffraction grating.
This prism is made using optical glass and will demonstrate that white light is made up of the colours of the rainbow. This is known as a spectrum. In the 17th century Sir Isaac Newton was the first to prove that white light was in fact made up of different colours. This prism is very good for producing rainbows from sunlight, but if you want more control, try our Rainbow Spectrum kit.
Rainbow Spectrum Kit This kit - produced by Curious Minds - enables you to create spectra in the absence of bright sunlight, using a glass lens together with a prism or diffraction grating, and a white light. The instruction booklet contains several experiments, and explains enough science to understand the results. Newton would have been delighted!

This prism is made using optical glass and will demonstrate that white light is made up of the colours of the rainbow. This is known as a spectrum. In the 17th century Sir Isaac Newton was the first to prove that white light was in fact made up of different colours.
He used a glass prism in his experiments.
The prism is 5cm (2 in) long. Each side is about 2.5 cm (1 in).

Holographic diffraction grating film is used to break up white light into all the colors of the spectrum. It is an ideal choice for spectroscopy experiments, since holographic gratings exhibit significantly sharper diffraction orders than their ruled counterparts by reducing the amount of stray light produced. This results in an increased ability to view absorption and emission lines, with high..

How do you make a rainbow? The most common method is to put a prism in a sunny window. If you don't have bright sunshine and try to use artificial light such as a desk lamp or torch, the results are most likely to be disappointing. There are other, more reliable, methods. This kit provides the apparatus and instructions for creating clear spectra in the absence of bright sunlight.

Students will get to see and appreciate the prismatic qualities of light by using this diffraction grating spectroscope kit.
White light can be separated into all of the colours of the spectrum by a prism or a diffraction grating. The spectroscope is an instrument used to observe this colour separation. It uses a diffraction grating with a narrow slit in the front through which light enters..
