A lamp type device associated with a reflector illuminates a receiving surface of a light guide/former. An emitting surface of the light guide/former arranged proximate to a film, has substantially the dimensions of the film zone to be illuminated. The light guide/former is a single-piece part comprising two opposite planar surfaces, whereon one is receiving and the other emitting. The invention is useful for a device providing an intense and homogeneous light beam for film scanning analysis.
