Prism – Premium Equilateral Glass Prism 50mm [1869]

This Premium Equilateral Glass Prism is a high‑quality optical teaching aid designed for accurate and reliable classroom demonstrations. Manufactured from completely bubble‑free glass, the prism features precisely worked angles and polished, non‑optically worked surfaces, ensuring consistent and dependable performance in educational environments.

The prism has nominal equilateral angles of 60° × 60° × 60°, making it ideal for investigating how light is refracted and dispersed when it passes through transparent materials. Its slightly bevelled edges improve durability and handling safety, particularly important for frequent use by students.

With a generous 50mm size, this prism allows clear observation of light paths, colour separation, and angular deviation, helping students visualise key optics concepts with confidence.
