Light Guide Demonstrator
Product Code : JA-LOE-7897
The Light Guide Demonstrator (SKU JA-LOE-7897) is an S-shaped acrylic bar, 220 x 20 x 20 mm, that carries a beam of light around its bends by total internal reflection when used with a ray box. The bottom face is painted white to make the path of the light easier to see, so a class can follow the beam as it reflects from wall to wall. This total internal reflection light guide helps students understand the principle behind optical fibres and optical communications, and is manufactured in India by JaincoLab.
Specifications
The demonstrator is a single S-shaped acrylic bar measuring 220 x 20 x 20 mm, with its bottom painted white to aid visibility, designed to be used with a ray box.

Applications of the total internal reflection light guide
The light guide is used in ray optics lessons to show that light entering one end of a transparent bar can be trapped inside it by total internal reflection and led around curves, which is the working principle of optical fibres.
- Demonstrating total internal reflection with a ray box beam
- Introducing optical fibres and optical communications
- Showing how the angle of incidence at a bend decides whether light escapes
- Linking refractive index and critical angle in senior-secondary optics
- Class demonstrations alongside prisms and semi-circular blocks
