An assembly of ray-projectors, lenses and mirrors that mount directly to the chalkboard, via suction clamps (also available in magnetic). Perform experiments directly on the board, chalking in lines, measuring angles and calculating formulas. Components also sold separately.

Klinger BlackBoard Optics™ is a unique approach to teaching principles of optics and properties of light. Experiments in refraction and reflection are performed directly on the blackboard without darkening the room. Visibility is assured because of the large acrylic lenses. The special ray projectors may be arranged to form a pencil beam of light or a divergent cone by means of a fingertip adjustment. With the components in place, the instructor can chalk in axes, normals, tangents and equations directly on the chalkboard.
