The invention relates to an inspection device (1) for monitoring bottles (2) or similar containers, comprising at least one lighting unit (6) and at least one camera (7), wherein the at least one lighting unit (6) is arranged above the bottle (2) to be examined. In order also to be able to examine bottles (2) of different colours, and in order to be able to detect, for example, also rust deposits (4) reliably, according to the invention the lighting unit (6) is designed as a light source circuit board (6), the light sources (8) of which emit light that can be changed at least in colour to a bottle colour determined in the region of a bottle mouth (3), wherein the light sources (8) are arranged in radially spaced light source rings (9), each concentric about a midpoint of the light source circuit board (6), and emitted light is coupled at least partially into the interior of the bottle mouth. By means of LEDs, light modulated in colour at least to the bottle colour is expediently coupled into the inner wall of the bottle mouth (3). |
