A machine for inspecting the heal code of a bottle. The bottle is supported vertically at an inspection location and a camera having an imaging area is located vertically beneath the bottle. A horizontally disposed annular ring light directs an annular beam of light upwardly at a heal code of a supported bottle and light reflected from a heal code is reflected by an annular concave surface located concentrically below the annular ring light to the imaging area of the camera.
