Abstract

The present invention is directed to inspection of sealing surfaces of containers for defects which may prevent proper sealing of the container. The present invention provides an inspection apparatus, system, and method for dark-field machine vision inspection of containers, such as glass containers or other containers having a sealing surface. The illumination system provides a dual directional helical illumination technique, which enhances the ability to distinguish any defects in the sealing surface area. The illumination system may also provide the ability to adjust the diameter of a circular illumination pattern, so as to allow adjustability and optimization of the illumination characteristics for differing container configurations.
