Abstract

This invention is directed to the separation of electromagnetic radiation into a, plurality, of selective wave length bands or colors. The term color separation, broadly applied, is meant to be the separation of primary and secondary or complementary wave lengths or colors for the purpose of geometric imaging. Such color separation is achieved, substantially, instantaneously, without the loss of wave length energy or color intensity by a novel means of reflection, transmission and color filtration. The separated colors or selective wave length bands can be, substantially, instantaneously, recreated as a geometric image or can be recorded for later recreation as a geometric image such as by photographic or movie films or by tapes; lithographic plated or engravings. Also, the separated colors or selective wave length bands can be used in making printing plates, directly, without using film.
