set of 3 Prisms

The Set of 3 Prisms is a set of three glass prisms for use on the Prism Table on Stem or the Kroncke Optics Prism Table K. The prisms demonstrate the design of an achromatic prism and a direct vision prism. The prisms can deflect light beams differently based on their shape. Combining them with one of the prism tables enables them to be used with optical riders and optical benches for a range of demonstrations and experiments.

contents of the set of 3 prisms

The set consists of a thin flint glass prism, as well as thin and thick crown glass equilateral prisms. The two thin prisms deflect a light beam equally strongly but with different dispersions. Moving them closer together in the light path results in a direct vision prism which decomposes light into its spectral components without deflecting it.

The thick crown glass prism has the same dispersion as the flint glass prism, but deflects the light beam twice the distance. This permits configuration of an achromatic prism which deflects light without without splitting it into a spectrum.
