Abstract: Method for determining the topography of the surface (2) of an ophthalmic lens (1) in which the lens is illuminated with a light beam to form a light spot or intersection plane (13) on the lens surface and the surface is then scanned with said beam. The shape of successive images of the light spot are recorded with an optical recording device and the surface topography is determined from the recorded images. An Independent claim is made for a device for determining the topography of an ophthalmic lens surface.

Abstract: Procedimiento para remarcar o resaltar la forma de un contorno (5, 6, 9, 10) de una lente oftálmica (1) previamente mecanizada, que incluye las operaciones consistentes en: - iluminar una cara óptica (2, 3) de la lente (1) por medio de un haz luminoso (15) plano para formar sobre esta cara (2, 3) una mancha luminosa 5 (16) lineal, de manera que el haz (15) desborde de dicha cara (2, 3) e ilumine dicho contorno (5, 6, 9, 10); - formar sobre medios de recepción óptica (18) una imagen (21) de dicha mancha luminosa (16); - arrastrar en rotación la lente (1) alrededor de un eje (A); - barrer el contorno (5, 6, 9, 10) por medio del haz luminoso (15); - remarcar conjuntamente sobre los medios de recepción óptica (18) las posiciones sucesivas de al menos un punto singular (S, T, V) de esta imagen (21) correspondiente al punto iluminado (S', T', V') de dicho contorno (5, 6, 9, 10); - deducir de ello la forma de dicho contorno (5, 6, 9, 10)

Abstract: During the chamfering of the edge (6) of the lens, the edge is scanned by a plane light beam (23) which forms a linear light mark (24). An image of the light mark is formed in an optical reception system (26). This image is used to monitor and control the machining process. The procedure provides chamfering for the edge (6) of a an ophthalmic lens (1), during which the edges of the lens are removed successively in order to define the chamfered edge (6). During this process, the edge (6) of the lens is scanned by a plane light beam (23) which forms a linear light mark (24). At the same time an image of the light mark is formed in an optical reception system (26). From this it is possible to deduce the successive positions of the image, and hence the position of the chamfer formed on the edge of the lens. The process is carried out whilst the lens is mounted to rotate about an axis (A1), whilst its edge is in contact with the chamfering tool. The relative position of the lens and the tool are adjusted as a function of the light mark detection.

Abstract: Procedimiento para biselar al menos un borde (5, 6) de una cara óptica (2, 3) de una lente oftálmica (1) que comprende una etapa de registro en la cual se registran las combaduras sucesivas (á) de la cara óptica (2, 3) cerca y a lo largo del borde (5, 6) a biselar, caracterizado porque, en la etapa de registro se barre el borde (5, 6) a biselar por medio de un haz luminoso (23) plano que forma en la cara óptica (2, 3) una mancha luminosa (24) lineal, se forma simultáneamente en medios de recepción óptica (26) una imagen (29) de la mancha luminosa (24), se deducen de las posiciones sucesivas de esta imagen (29) las combaduras sucesivas (á) de la cara óptica (2, 3) cerca del borde (5, 6) y porque comprende una etapa de biselado en la cual se lleva la lente (1) trasladada en rotación alrededor de un eje (A1) en contacto a través de su borde (5, 6) con una herramienta de biselado (9) y se comanda el posicionamiento relativo de la lente (1) y de la herramienta (9) en función de los registros efectuados.

Abstract: Method for determining the shape of outlines (5, 6) of a machined ophthalmic lens (1) has the following steps: illumination of the optical face (2, 3) of the lens using a light beam (15) that generates a linear light spot (16) on the lens surface adjoining its outline; imaging of the light spot using an optical receiver (18); rotating of the lens around its optical axis (A); scanning of the outline (5, 6) using the light beam; simultaneous recording of successive positions of at least one singular point corresponding to a point illuminated on the outline; and deduction of the outline shape. The invention also relates to a corresponding device.
