Equilateral Glass Prism, 3.2 cm × 10 cm

This equilateral glass prism is a classic optics tool for showing how white light separates into the colours of the visible spectrum. As a beam passes through the solid triangular glass body, it refracts and disperses, producing a bright, clear spectrum — perfect for hands-on demonstrations of refraction, dispersion and total internal reflection in the physics or general-science classroom.

Features

• Solid optical-grade glass for bright, well-defined spectra
• Equilateral triangular cross-section with 3.2 cm sides
• 10 cm length projects a wide, easy-to-see spectrum band
• Great for experiments in refraction, dispersion and spectrum formation
• Durable, reusable demonstration tool for teachers and students
