Abstract
Improved systems for optical inspection are provided. The improved systems use modified camera boxes to provide increased, and more uniform, illumination of the objects being inspected through the use of illuminator windows. The lens arrangement of the improved camera boxes is contained within a self-contained, sealed housing that is separate from the camera to prevent particle contamination of the lens arrangement and provide improved flexibility during installation of the camera boxes on the inspection systems. The self-contained housing also provides for a reduction in the space required for the camera boxes. The light receiver of the housing is provided with the capability for preventing particle contamination of the receiver itself.
