Inspection apparatus for bottles or similar containers

摘要

The device (1) has at least one illumination device (4) to the side of a conveyor (3), an electronic camera (9) and an optical arrangement (5,8) for producing at least two images of the respective container (2) from at least two different directions. The optical distance between the container at the inspection position and an objective of the camera is selected for each image taking into account the focal length of the objective and the optical arrangement so that an essentially parallel arrangement of the light between the container and the objective is achieved for each image.
