ABSTRACT:
The present invention relates to an inspection system for the automatic inspection of ophthalmic lenses, preferably in an automated lens manufacturing line. The inspection system provides a phase contrast imaging unit and an inspection method using said phase contrast imaging unit designed to recognize defective lenses with an improved degree of reliability but that does not falsely sort out perfect lenses.
