Abstract: A method for producing an optical product, such as a lens of a mobile phone, wherein in the production and further processing method an identifier (2) identifying the product is achieved, by which the genuineness of the product is verifiable.

Abstract: The invention relates to a method for coating the plastic casing and/or lens of a portable electronic device, in which the plastic casing and/or lens is coated by laser ablation with the plastic casing and/or lens shifted in a material plasma fan ablated from a moving target in order to achieve a coating having as regular quality as possible. The invention also relates to the product produced by the method.

Abstract: The invention relates to a method for producing a workpiece comprising one or more detachable optical products and to a preferably planar workpiece comprising detachable optical products. The method of the invention allows for efficient production of workpieces comprising high-quality optical lenses by combining e.g. techniques used in the production of CD/DVD discs and coating units based on laser ablation. The finished optical products are integrated in the workpiece, but they can be removed e.g. by water abrasion, laser cutting, milling or sawing.
