Light Demonstration Guide
Product Code : JA-CE-4329
The Light Demonstration Guide (SKU JA-CE-4329) is an S-shaped acrylic bar that shows students how light can be carried round bends by total internal reflection, the principle behind optical fibres. A beam shone into one end follows the curves of the bar and emerges at the other end. This acrylic light guide for total internal reflection is used in school and college physics lessons on refraction and optical communication, and JaincoLab supplies it with a white base for better visibility.
Specifications
The light guide is an S-shaped bar of clear acrylic measuring 205 x 22 x 20 mm, mounted on a white-finished base that makes the path of the light easier to see during a demonstration; the light source is not part of the listing.

Teaching total internal reflection with the light guide
Light entering the end of the bar strikes its inside surfaces at angles greater than the critical angle, so it is reflected along the bar instead of escaping; students see the beam follow both bends and link this to how optical fibres carry signals.
- Demonstrating total internal reflection in secondary-school physics
- Introducing the principle of optical fibres and optical communication
- Showing the effect of the critical angle when the bar is bent more sharply
- Science exhibitions and classroom optics displays
