Highly durable, polished acrylic with smooth, rounded edges, these prisms will last for years. Equilateral prisms are meant for dispersing elements, or white light, into a spectrum of colors creating a rainbow effect. Great for science experiments to demonstrate bending light. With 3 equal sides at 60 degree angles, there are 2 spectral diffractions. They can also be used for wave length separations, and special rainbow lighting effects in photography.

FEATURES:

• Made from high quality, clear acrylic sheet
• Polished with smooth edges
• Use for science experiments in physics and optics
• Easy to handle for photography effects
• Set of 2 prisms, 4" long and 6" long
