A production line (PL) for the production of ophthalmic lenses () comprises The manufacturing module (MM) comprises a plurality of manufacturing stations (). At least one of these manufacturing stations () is configured to apply a lens identification code () to the respective lens. The lens identification code () includes information indicative of the type of the respective lens. Either the inspection module (IM) or the packaging module (PP) includes a lens detection station () configured to read the lens identification code () applied to the respective lens and to detect the type of the lens from the lens identification code () read from the respective lens in order to determine whether the type of lens detected actually is the type of lens which is expected to be detected by the lens detection station () at that time.

Modular production line for the production of ophthalmic lenses

A lens inspection module comprises: Cleaning shuttle comprises a driving unit a cleaning head, a suction unit, and a tube connecting cleaning head and suction unit. Cleaning head is spaced apart from suction unit and driving unit in the transportation direction and is pivotally arranged about a pivot axis. Cleaning head may comprise a distance sensor for detecting the distance between cleaning shuttle and transportation shuttle. Driving unit is configured to change the speed of the self-driving cleaning shuttle when the distance between the cleaning shuttle and the transportation shuttle is shorter than a predetermined threshold distance.

Lens inspection module

Disclosed is an inspection and system method and system for determining the orientation of a contact lens on a lens support, particularly in an automated contact lens manufacturing line.

Contact lens inspection method and system

A cuvette system () for use in the optical inspection of ophthalmic lenses comprises at least one receptacle () for accommodating an ophthalmic lens. The receptacle () has a longitudinal extension and an opening () arranged at one longitudinal end thereof. The receptacle () is adapted for containing a liquid. The cuvette system further comprises at least one inspection window () having an inspection surface (). The inspection window () is arranged stationary and from the receptacle (). The inspection window () is adapted for being joined to the receptacle () at the opening () of the receptacle () such that the inspection surface () of the inspection window () is immersed in the liquid. The inspection window () is further adapted for being removed from the opening () of the receptacle ().
