A diffractive color filter, comprised of proximately disposed diffraction grating and lenticular lens structures, which may be embossed on plastic sheet, cooperates with an imaging lens to produce color stripes or color spots of an image on a photosensitive surface. The diffractive color filter may be used, for example, as a color-encoding stripe filter of a color TV camera.
