Abstract
Apparatus for inspecting containers for foreign matter so as to insure the same being free of such matter that could affect the contents when the containers are filled, such apparatus incorporating an inspection system in which a prism is able to rotate non-collimated light without introducing distortion since it does not depend on plane wave fronts and is thus able to greatly expand the field of view, thereby providing more dependable detection of foreign matter at the center and in the peripheral areas of container bottoms and lower side walls.
