Ray box, simple, safe and sturdy source of projected light for many classic optics experiments, produces parallel convergent rays across a plane horizontal surface and the rays are intense enough to be traced in natural light. Built in solid aluminum extrusion casing, 100-240V 50/60 Hz
Ray optics apparatus, components,lined with magnetic foil or furnished with a magnet holder and can be easily mounted and aligned on the white board. This apparatus permits a wide range of experiments demonstrating ray optics without the need for a dark room
Reaction Timer allows you to precisely quantify a person's reaction time by recording how quickly they can flex their muscles in response to a stimulus, Stimulate with two different colors of light in 3 different locations to test for visual reaction time
