Abstract: A vessel inspection device for examining a vessel for damage in a filling region or opening region having a bead or a bulge, which bead or bulge forms an undercut, has a camera, an objective associated with the camera, and a further optical element, which can be adjusted and fixed in place in terms of their distances from and their orientation relative to one another and relative to an image recording axis, and the optical element is a mirror in the form of a ring mirror that widens toward the camera, the longitudinal section of which, containing the image recording axis, has the form of an ellipsis portion that is inclined relative to the image recording axis and displaced radially outward, wherein the ellipsis portion has two semi-axes that deviate from one another, and the device can be moved into an inspection position relative to the vessel to be inspected for inspection of the filling region or opening region of the vessel, during every inspection procedure.
