More Information
Summary:Improved systems for optical inspection are provided. The improved systems use modified camera boxes (10) 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 (12) 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. Illumination light is transmitted along fibres (62), into illuminator (44) and through windows (50), which act as waveguides, and exit as light rays (64). The reflected image, in the form of light rays (66) is captured by mirrors (48) and reflected through windows (50) to prism (36). Prism (36) takes each subimage and directs it to a central focal point, which may occur at a folding mirror (52) or on the camera lens directly.
