Semi‑Circular Acrylic Block – 100 × 18mm (Fully Polished)

This high‑quality Semi‑Circular Acrylic Block is made from crystal‑clear acrylic with all faces fully polished to ensure exceptional optical performance. Measuring 100mm in diameter and 18mm thick, it provides a precise and durable component for a wide range of light and refraction experiments in school science laboratories.

The semi‑circular shape allows students to explore how light behaves when moving between curved and flat surfaces, making it an essential resource for hands‑on optics investigations.

Key Features

• Clear acrylic construction for excellent light transmission
• Fully polished surfaces for high optical clarity and minimal distortion
• Dimensions: 100mm diameter × 18mm thickness
• Durable, lightweight, and safer than glass for student use
• Ideal for curved‑surface refraction and ray‑tracing demonstrations

Ideal for School Science Lessons & Experiments

Perfect for KS3, GCSE, and A‑Level physics, this semi‑circular acrylic block helps students explore a wide range of optics principles. It is commonly used for:

• Refraction demonstrations with ray boxes and lasers
• Investigating how light bends when entering curved vs. flat surfaces
• Measuring refractive index of acrylic using practical methods
• Exploring total internal reflection and critical angles
• Understanding lens behaviour, ray deviation, and optical geometry

Clear, durable, and classroom‑ready, this polished semi‑circular acrylic block is an essential resource for accurate and engaging optical investigations in school science lessons.
