A method for inspecting a medical container made of a light transmissive material. The method includes scanning a portion of the medical container to be inspected, by a white light emitted from a confocal chromatic system; detecting light reflected by the portion of the medical container by the confocal chromatic system; and determining whether a particle is present or not in or on the said portion of the medical container, based on a detection result obtained by the confocal chromatic system.

Method for inspecting a medical container

An inspection system having a light source able to illuminate a transparent cylinder, a mask able to block at least part of the light from the light source, the light source and the mask arranged such that, when the transparent cylinder is positioned in the system for inspection, the light source, the mask and the transparent cylinder are substantially aligned along an inspection axis perpendicular to the longitudinal axis of said transparent cylinder and the mask is interposed between the light source and the transparent cylinder to prevent illumination of a first portion of the transparent cylinder having a width smaller than the diameter of the transparent cylinder while allowing illumination of a second portion of the transparent cylinder, the mask configured to provide a contrast with a particle present in the first portion of the cylinder and illuminated by light refracted by the second portion of the cylinder.

System and method for inspecting a transparent cylinder

An inspection system for detecting a particle in a transparent cylinder having a longitudinal axis and a diameter includes a light source able to illuminate a transparent cylinder, a mask able to block at least part of the light coming from the light source, the light source and the mask being arranged such that, when the transparent cylinder is positioned in the system for inspection, the light source, the mask and the transparent cylinder are substantially aligned along an inspection axis perpendicular to the longitudinal axis of said transparent cylinder and the mask is interposed between the light source and the transparent cylinder so as to prevent illumination of a first portion of the transparent cylinder having a width smaller than the diameter of the transparent cylinder while allowing illumination of a second portion of the transparent cylinder, the mask being configured to provide a contrast with a particle present in the first portion of the transparent cylinder and illuminated by light refracted by the second portion of the transparent cylinder.
