The large lenses, mirror, prism, ad light sources contained in the Blackboard Optics Kit can be secured to any classroom blackboard. Actual experiments and measurements are performed directly on the blackboard without darkening the room. The teacher can chalk in axes, normals, tangents, virtual rays, and other information.

The kit contains 2 ray projectors and holders, 3 clamping bars, a plano-convex lens, a plano-concave lens, a semi-circular lens, a parallel-sided block, a right angle prism, 2 plane mirrors, a curved mirror, and a spare projection lamp. Note:

This kit requires a 12 V, AC power source (please see index).
