Equilateral Acrylic Prism, 63mm Length, 63mm Faces

This equilateral prism measures 2.5 inches (63mm) in length with 2.5-inch (63mm) faces and 60-degree angles. Made from durable, highly polished acrylic, it refracts white light into a visible spectrum of colors. The prism creates a rainbow when illuminated with a narrow beam of light, such as from a smartphone LED directed through a slit in dark paper. Suitable for physics experiments in optics, light refraction, spectrometry, wavelengths, and photography lighting effects.
