Light Box with Laser Beams. Five or three parallel bright and sharply defined diode beams 1.6cm apart can be selected for demonstrating the bending of light rays by reflection, Focusing effect, Reflection with mirrors, Fresnel reflection, Monochromatic character of laser light, Total Internal refection. A great tool for demonstrating optical ray paths - it can turn optical ray diagrams found in science and physics books into visual reality.
The Laser Ray Box consists of five 0.75 mW, 650 nm semiconductor diode lasers, each emitting a highly visible light beam. Beams are parallel and can be seen in most well-lit rooms. Energy is provided by a rechargeable NiCd battery.
Has a magnetic back for us on any magnetic vertical surface such as whiteboards, for classroom demonstrations.

WARNING: Do not shine beams into eyes.
