description Process for the production of a multipoint light guide and products obtained according to this process. This process consists of placing in a mold a bundle of plastics optical fibers obtained by drawing, said fibers being parallel and adjacent to one another and wherein the mold - bundle assembly temperature is homogeneously raised, in order to increase the diameter of the optical fibers until they fill the entire interior of the mold and e.g. assume a hexagonal shape, the thus treated bundle of optical fibers forming the light guide. It in particular makes it possible to obtain multipoint light guides combining both a transmission of images with a unity magnification and the enlargement or reduction thereof.
