ABSTRACT OF THE DISCLOSURE An isotropic light source produces uniform illumina- tion of a generally planar object to be visually inspected by a microscope such as a P.C. board having an irregular specular surface. Detrimental dark spots which are normally produced are eliminated by providing a skewed beam- splitter between the microscope and the viewed surface, which beamsplitter redirects light directly at the object along or near the optical viewing axis. The isotropic light source is a light integrating cavity in a first embodiment and a pair of fluorescent lamps in a second embodiment.
