ABSTRACT:
An illumination device for illuminating an object to be observed, by a machine vision camera or the like for example, with a continuous diffuse wide angle light which is supplied along the observation axis of the machine vision camera. The illumination device contains a light source to illuminate a curved beam splitter and a diffuser is located therebetween. The diffuser is mounted inclined with respect to the observation axis and the curved beam splitter minimizes the height of the illumination source and facilitates supplying a more uniform field of illumination to the object to be observed. The inclined diffuser only indirectly illuminates of the object to be observed.
