ABSTRACT:
The method and apparatus for providing a continuous, uniformed, diffused light environment for use in conjunction with an electronic machine vision or manual microscope inspection system, particularly for inspection of specular surfaces such as ball bearings, reflective packaging and other shiny surfaces. The illumination device includes a source of light which is associated with at least the secondary diffusers to provide secondary diffused illumination, of an object to be observed, substantially along the observation axis of the object. The same light source may also illuminate a rear surface of the primary diffuser. The height of the illumination device is approximately three and one-half times the clear aperture dimension of the illumination device or less. The illumination devices is arranged to provide uniformed illumination of the object with light which is equal in intensity and character to facilitate accurately viewing of the entire area of the object to be viewed.
