Abstract:
A device and method for inspecting glass containers and particularly the finish of glass containers is provided. The glass container inspection device includes a rotator rotates a glass container located in an inspection location at least 360 degrees. A first laser source produces a first laser beam which is directed towards the inspection location to form an angle of incidence with the selected glass container being greater than or equal to a critical angle for producing internal reflection of the first laser beam within the selected glass container. A camera is directed at the inspection location to detect light that escapes from the selected glass container as a result of the internally reflected laser beam intersecting a defect in the selected glass container.
