Self contained acrylic refraction tank used to measure and study the refraction of light. This device allows incident and refractive rays to be easily seen and measured. Features a 650nm laser light source that is magnetically attached to an adjustable arm that rotates, and can be fixed at any point around a graduated circular scale. Setup is simple with built in leveling screws on the feet. Simply add water to the fill line, attach the magnetic laser and you are ready for a simple and effective demonstration. Ships complete with batteries installed in laser. Instructions included.
The apparatus is very good, especially the new type of laser.
My question: My old type of laser was broken recently although the the part of tank was fine. Could you sell only the laser for us? If possible, please tell us the price.
