Process and apparatus for the continuous or semi-continuous coating of eyeglass lenses

摘要

Lenses are brought individually or in pairs on a transport device (12) to a continuous vacuum apparatus (1) equipped with a rotating substrate carrier (3). The eyeglass lenses (13) are introduced through a system of locks (15) into the continuous vacuum apparatus (1), where they are coated in at least one controllable coating station (5, 6, 7) with at least one transparent layer and then sent back to the transport device (12). The eyeglass lenses (13) are given codes (18), and the codes are read by a code reader (19). The coating parameters of the individual coating stations (5, 6, 7) and the drive of the substrate carrier (3) are controlled by the code reader (19).
