This Ray Box is a simple, safe, and sturdy source of projected light for many classic optics experiments. Best of all, you don't need a completely dark room to conduct optic experiments due to its high-intensity light!

Color Mixing apparatus - 3 LED Lamps that project Red, Blue, Green light.

This ray box is ideal for optical demonstrations in the classroom.

Study optics with this complete kit while learning about light, refraction, reflection, convex and concave lenses, and focal length.

Experimentally verify Malus' law.

Demonstrate the optical principles of lenses and mirrors.

Measure Brewster’s angle for a given dielectric dispersive medium.

This is a complete optical bench system at an affordable price.

This laser ray box has several modes, with 1, 3, or 5 beams.

This laser ray box is adjustable, magnetic, and bright enough to use in ambient light.

This updated Ray Box uses five super bright LEDs for bright, white rays that are clearly visible.

Find the concentration of a liquid using the samples of known concentration using the Beer-Lambert law.

This laser ray box uses cylindrical LED lenses to focus the beam.

An advanced laser ray box that clearly demonstrates the optical axis.

Map light intensity vs. position for various slit geometries.
