Quality Craftsmanship

Our prisms are made with K9 optical glass. They are checked for clarity and imperfections during the manufacturing process. Our prisms are hand sanded and polished to our specific size requirements to maintain consistency and quality. Our prisms are slightly wider than the competition to make them easier to hold and use.

All of our prisms come in our padded satin lined box.

How does a prism create a rainbow?

When light moves from air into the glass of the prism, light refraction occurs. The design of the prism causes the light to change direction. A ray of light is made up of many wavelengths of light. Each wavelength passes through the prism with different resistance than the other light waves. The different wavelengths normally travel together but get dispersed passing through a prism and we can see them separately as a rainbow.

Prisms are not just for science class and fun light experiments either. Both amateur and professional photographers can use prisms to create interesting effects in their pictures. See below for more information on how to make a rainbow and the fractal lens effects you can create with our prism.


Place the triangular prism under the sun or use a beam of white light. Rotate the triangular prism to make the light shine on one plane (any one of the three planes can be used). Seven rainbow colors (red, orange, yellow, green, green, purple and blue) will appear on the wall. The child can initially obtain the perception experience of light refraction by operating the triangular prism, stimulate the child’s curiosity and exploration heart, and make the child fully understand the phenomenon of light.
