E8A45652 35 x25mm E. Light Guide Demonstrator
For showing how the phenomenon of total internal reflection may be used to confine light within a guide or fibre, thus leading to an appreciation of the principles of optical communications.
Comprising an acrylic bar 220 x 20 x 20mm, formed into a shallow ‘S’ shape. Whilst the shape of the bar prevents the direct passage of a light ray, if such a ray (from a light box or laser) is introduced into 1 end, it can be seen to be reflected several times, from the internal surfaces of the bar, to emerge from the other end. The lower surface of the bar is painted white to aid visibility of the path of the light ray.
E8A45688 F. Acrylic Light Pipe
This hard acrylic 13mm diameter light pipe is 610mm of pipe coiled up at one end to demonstrate light transmission end to end. It transmits light like fibre optic cable.
