Abstract

An arrangement for illuminating objects wherein a large number of objects are rapidly and continuously transported past one or more stations, each illuminated by a cylindrical, integrating Lambertian reflecting/diffusing cavity having one or more like light sources therein so as to generate and project a highly intense, highly uniform and highly diffuse beam of illumination, while incorporating optical guide means to couple said illumination beam to the face of the objects at said station and to couple the reflected image of the object back to the cavity.
