Lenses Set
Six 5-cm diameter lenses cover all of the permutations of curvature from positive
power biconvex to negative power biconcave. The power of the symmetrical lenses
is 5 diopters. These lenses are excellent for the study of Gaussian optics and the
investigation of lens combinations to build simple instruments such as telescopes.
Lenses come in a varnished wooden case with a latched lid.

Neutralizing Lens Set
The two lenses in this set are a match. Both lenses are 38 mm in diameter. With a
focal length of 15 cm, they can be used to demonstrate the reverse optic effects of
these two lens types. Each comes individually wrapped and in a labeled storage box.
