1. Triangular equilateral prism with 60-degree angles. Made of high-quality, polished material2. The glass prism measures 2.5? (63mm) in length. Each face measures 2.5? (63mm)3. Excellent for physics classrooms. Ideal for a variety of experiments in optics, light refraction, spectrometry and wavelengths4. Great for photography lighting effects. When used with any standard light source, these prisms will create a rainbow of colour.
