Abstract
A device (V) for optical inspection of open beverage cans (D) having a light source (Q, Q') positioned outside the can, a reflector (R) for reflected light from the inside of the can, arranged between the light source and the opening in the can, a camera (E) which is alighed with the reflector, and an optical device (P) with which the light (11) from the light source (Q, Q') can be projected from above through the opening (4) in the can directly onto the bottom (B) of the can, whereby the can collar (K) can be illuminated from the bottom (B) of the can on the inside. In this method, the light is bundled and directed through the narrow section of the reflector, then expanded after the reflector and projected directly onto the can bottom (B) centrally as the light spot (13, 13') displacing the light source (Q, Q') into the can in order to illuminate the inside wall of the collar from beneath from the light spot and to image it by the reflected light.
