Ray Box

The Ray Box is an excellent instrument to demonstrate simple light experiments to students. Powered by 4 (D) batteries, the user can change between one-slit ray and three-slit rays with the simple touch of a button. The white LED bulb produces bright lines of light that can be clearly observed in the day time classroom. The student can project parallel, divergent, and convergent light rays through lenses onto a white background. This unit contains a special built-in focusing mechanism.
