Ideal for introductory ray optic studies, this updated Ray Box uses five superbright LEDs for bright, white rays that are clearly visible.
The white rays can also be used for color studies, unlike the monochromatic laser beams of other ray boxes.
The superbright LEDs also use less power and run much cooler than an incandescent lamp, providing a much longer life with no burned out lamps to change. Designed for easy student use, the ray box does not require any focusing adjustment simply plug it in and select from one, three, or five rays. It operates on safe, low voltage from a wall mount power supply for your safety. 110 VAC.
