Equilateral Glass Prism, 6 x 1"

This 6-inch (150mm) equilateral glass prism features 1-inch (25mm) faces and is made from optical quality glass. The prism creates a rainbow with any standard light source by refracting white light through its triangular cross section. Designed for physics and educational use; minor cosmetic imperfections may be present but do not affect optical function. Suitable for teaching optics, light dispersion, and photography lighting effects. Use a phone LED with a black slit paper for striking rainbow demonstrations.
