ABSTRACT:
A rainbow creating device comprises optical conductors through which light rays consisting of visible light ray components are transmitted. A lens is placed opposite the respective light-emitting ends of the optical conductors for converting the light rays emitted from them to parallel light rays. Prisms are placed for receiving the parallel light rays from the lens and for effecting the spectroscopic separation of the parallel light rays.
