The Basic Optics Light Source is an excellent source for a variety of optics experiments. A single 10-watt quartz-halogen bulb provides bright, easy-to-see illumination without a lot of heat. By turning the box to a different side, it becomes a:
Crossed Arrow Object with Metric Scale: Ideal for showing images, focal point, and magnification.
Bright Point Source: The very small filament of the halogen bulb provides an excellent point source for experiments involving shadows or the Inverse Square Law.
Three Primary Colors Source: The red, green, and blue filters produce three rays of light that can easily be combined with a lens to study color mixing.
One, Three, or Five Ray Sources: Simply rotate the knob in front of the Light Source to vary the number of rays produced.
