The Optical Glass Lenses Set for physical science and physics over all of the permutations of curvature from positive power biconvex to negative power biconcave.
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.
