Method and apparatus (1) for inspecting containers (5) with optical vision means (2) in combination with planar convex and/or double convex lenses (6) having non spherical section so shaped and positioned as to deviate according to predetermined angles light rays coming from the container (5), to allow the simultaneous vision, in a single image, both of parts of the container (5) that are directly visible, and of parts of the container (5) that are not directly visible by said vision means (2). |
