Neutralizing Lens Set

Matched convex/concave lens set will enhance understanding of refraction.

Two matched lenses, one concave and one convex, when placed together, result in no magnification at all - like flat glass. Let students independently find the focal lengths of each lens and predict what will happen when they are combined. Focal length +/- 150mm, 38mm diameter, made of glass.

Lens/Mirror holders not included.
