The bottle inspection device has at least one light source (3) and an image detector (2), coupled to an image evaluation device (2'). A one-piece optical block (4) is shaped to provide a full volume image of the bottle section illuminated by the light source at the image detector. Total internal reflection of the light rays is used, with the image evaluation device detecting any flaws in the examined bottle from this image. The optical block is made of a transparent material, with light entry and/or exit surfaces (A,E) positioned at right angles to axis of the examined bottle section. |
