Laser Refraction Tank w/Geometric Optics Demonstration Kit
by American Scientific

With its built-in laser light source, this demonstration kit allows students to visualize, measure and study the refraction of light. A water tank can be filled and used to create a surface that transmits and reflects, with the laser capable of rotating around the tank on a circular, graduated scale to see what the effect of different angles has on the beam.

The scale and laser can also be detached from the tank, and the different optical accessories of prisms and mirrors can be used in conjunction with the optical device to perform refraction and reflection experiments. There are four different prisms and two mirrors, as well as a splitter which allows the single beam of light to be transformed into multiple beams.

Also included is a detailed experiment guide.
