摘要:
A lamination machine (10) comprising: - a film support (16) for receiving a functional film (12) to be laminated, - an article support (18) configured to receive and position the optical article (14) in a predetermined orientation, and - an actuating member (20) configured to move the film support (16) and the article support (18) toward each other for laminating at a predetermined pressure the functional film (12) received in the film support (16) onto the optical article (14) received within the article support (18), wherein said article support (18) is a blocker support configured to receive a surfacing blocker (22) onto which the optical article (14) is to be disposed for lamination, said article support (18) being further configured to transmit laminating forces induced by said predetermined pressure to the lamination machine (10) during a lamination operation.
摘要:
The semi-finished lens (22) comprises a blank (23) formed in a first material having a first hardness, the blank (23) having an outline (33), a first face and a second face configured to be surfaced so as to constitute a first optical face of the ophthalmic lens, and a top layer (24) formed in a second material having a second hardness greater than the first hardness, the top layer (24) having an outline (34), a first face (29) and a second face (30), the second face of the top layer (24) being arranged on the first face of the blank. The outline (34) of the top layer (24) is equal to or included in the outline (33) of the blank (23), and satisfies to a predetermined dimensional selection criterion involving the final outline (32) of the ophthalmic lens.
摘要:
An optical article provided in a form suitable for simultaneous lamination of a pressure sensitive adhesive layer and of a thermoplastic film, the said optical article comprising a convex and a concave optical surface, wherein the convex and/or the concave optical surface is a receiving surface intended to receive the pressure sensitive adhesive on which the thermoplastic film is intended to be arranged and wherein the said receiving surface has an arithmetic average profile roughness greater or equal to 0.01 µm and less or equal to 0.3 µm and/or wherein the said receiving surface has a profile roughness root mean square slope greater or equal to 0.2° and less or equal to 1.2°. A method for manufacturing an optical device using said optical article.
摘要:
A device comprising at least a carrier layer (20), a counter-force liner (22), said carrier layer (20) and said counter-force liner (22) being adapted to receive a functional film (212) between said carrier layer (20) and said counter-force liner (22) in a predetermined receiving area. The carrier layer (20) and the counter-force liner (22) are larger than the receiving area, and the device comprises fastening means adapted to fasten, directly or indirectly, the counter-force liner (22) to the carrier layer (20) at least on a portion of a zone outside the receiving area.
