A foreign matter inspection system for a camera lens module comprises a pre-inspection loading part for loading a lens module to be inspected and transferring the lens module to a predetermined foreign matter inspection position; a foreign matter inspection part for inspecting whether or not foreign matters are attached to both sides of an IR cut-off filter and both sides of an ocular of the lens module transferred to the foreign matter inspection position; and a post-inspection loading part for transferring and loading the lens module finished the inspection. The foreign matter inspection part comprises a reflective inspection module for emitting first illumination light to the outer surface of the IR cut-off filter and collecting the reflected first illumination light to generate a first foreign matter image; a transmittable inspection module emitting second illumination light to the objective lens of the lens module and collecting the second illumination light emitted from the IR cut-off filter after transmitting the lens module to generate a second foreign matter image; and an analysis module for inspecting the foreign matters from the first and second foreign matter images. |
