Universal Light Source and Ray Box, SL-20, Dimensions: 150 x 75 x 75mm

The ray box SL-20 contains a light bulb that has a vertically placed straight filament. The SL-20 ray box can emit a large light beam or one, three or five parallel strong beams depending upon which magnetized card is placed on the front panel of the unit (4 cards included).
The SL-20 box allows the study of divergence and convergence of lenses and mirrors. Given the great intensity of the light bulb it is easy to demonstrate the light dispersion with a glass prism and a projection screen. Voltage input: 120 VAC with an adaptor (included).
Dimensions: 150 x 75 x 75 mm. Two-year guarantee.
