Abstract

A method and apparatus for automatic determination of a location and orientation of a finishing block to be attached to a lens. The lens has either visible reference features or invisible reference features associated with a prescribed or predetermined value of at least one optical characteristic of the lens, with respect to which reference features the location and orientation of the finishing block are in a predetermined geometric relationship. The apparatus comprises a support (3) for carrying the lens (A); a reference features finder (5) for obtaining a graphic image of the lens (A) if the reference features are distinguishable when imaged, and/or obtaining a mapping image of the lens (A) based on which the optical characteristic of the lens (A) may be calculated, if the reference features are non-distinguishable when imaged, and a computer (24) for processing the graphic and/or mapping image of the lens (A), to derive therefrom the coordinates of the reference features and to determine the location and orientation of the finishing block (1) based on their predetermined geometrical relationship with the reference features and using the coordinates of the reference features.
