Everything you need to conduct optical demos, labs and experiments, from the simple to the advanced, in one kit!

Designed and manufactured in Australia, this quality Light Box & Optical Set allows you to preform refraction, reflection, colour, and colour mixing experiments with ease.

The comprehensive set features an easy-to-use virtually unbreakable light box with an adjustable collimating lens, plus a full set of lenses, acrylic blocks, half-round and parabolic mirrors, slit plates, colour cards, and colour filters. Reflect, refract and colour blend light, observe and take measurements.

Here are just some of the things you can do with this comprehensive kit:

  • Create single or multiple parallel, convergent or divergent beams.
  • Blend up to three colors on a screen to study color mixing.
  • Create and test complex light paths from theoretical layouts.
  • Perform many more light and color experiments.

The Light Box & Optical set was designed back in 1971 and has undergone several improvements since that time (listed below). This original Australian kit remains the best quality and value for money worldwide.

The included instruction manual is packed with ideas for a broad range of experiments for almost every grade level. The kit includes a spare 12v, 36-watt bulb and special three-part molded styrene pack for safe, easy storage and transportation of the light box and all accessories. A power supply capable of producing 12 volts at 2 or 3 amps is required.
