ID Code: L6-02
Purpose: Show focusing of a circular lens.
Description: Parallel rays incident on a 12 inch diameter circular plastic disc converge at the focal point. Spherical aberration is clearly seen. Number of slits and their spacing can be changed by choice of slit baffle and distance of baffle from source. This cylinder can also be used to produce a nice rainbow; see Demonstration N1-44: RAINBOW - OPTICAL BOARD.
