Parabolic reflectors focus the light of the sun into a focal point in which a piece of paper can even be set on fire. Parabolic troughs have a focal line in which pipes or tubes, for example, can be heated in a particularly efficient manner. In this experiment, a black test tube that is filled with water is illuminated with a 120 W reflector lamp and the effect of the parabolic trough is studied based on various set-ups:
test tube in the focal line, out of the focal line, and set-up without a parabolic trough.


  • Part of a system solution - Easily expandable for further experiments
  • easy teaching by using the demo board for demonstration
  • Simplified implementation: all pre-settings already prepared
