Abstract
An inspection device which is compatible with in-line inspection of containers and reliably determines the presence or not of a defect of a container, has a lighting system arranged above an installation zone and being capable of providing an incident light beam, an image sensor connected to an image-analysis unit, and an optical system with a first primary reflection surface arranged above the installation zone and interposed between the installation zone and the sensor for forming on the sensor an image of a container ring surface to be inspected. Also included is a second primary reflection surface in the upstream field of vision of the sensor to reflect light beams, directly or indirectly in the direction of the sensor. The first and second primary reflection surfaces determine first and second portions of a downstream field of vision, which overlap in the inspection zone.
