Acrylic Triangular Prism – 90° × 60° × 30° (75mm)

This high‑quality 90° × 60° × 30° Acrylic Triangular Block is ideal for demonstrating key optical principles such as refraction, internal reflection, and light dispersion in school science lessons. Manufactured from durable, optical‑grade acrylic, it offers excellent clarity and impact resistance for reliable use in physics classrooms and laboratory demonstrations.

With a 75mm length, this triangular prism is perfectly sized for use with ray boxes, LED light sources, and lasers. Its precisely cut angles—90°, 60°, and 30°—make it suitable for a wide range of experiments involving the bending of light, critical angle investigations, and exploring how prisms refract and redirect beams.

Unlike glass prisms, the acrylic construction provides added safety and durability, making it an excellent classroom‑friendly choice for repeated handling by students.
