Nakamura Ray Box

The Ray Box is an excellent instrument to demonstrate simple light experiments to students. Made with dry cells, the user can change between one-slit ray and three-slit rays with the simple touch of a button. The tubular bulb produces a parallel light source. 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, a white plastic projection base, an acrylic mirror, and a beaker stand for conducting refraction through liquids.

SPECIFICATIONS
The Ray Box is powered by 2 D batteries.
