This invention relates to method and apparatus for inspecting glass containers and other types of containers having transparent or translucent sidewalls for defects, and especially to inspecting the finish portion of glass containers for defects such as horizontal checks. The entire finish portion is illuminated by diffused light and the check-type defects reflect light upwardly into an Erfle eyepiece which is then imaged onto a matrix-type light sensor.
