    Abstract: Dispositivo de fijación de un cristal oftálmico para su contorneado exacto, que comprende al menos un tope de arrastre (16a, 16b) que incluye una espiga central (24a, 24b) relativamente no deformable prolongada exteriormente por un collarín (26a, 26b) de material semi-rígido, elásticamente deformable, donde al menos el indicado collarín está conformado para presentar una superficie de aplicación (28a, 28b) apta para entrar en contacto con el indicado cristal y para deformarse para adaptarse a la forma de este último, caracterizado porque la indicada superficie se deforma por flexión libre, bajo el efecto de una fuerza de fijación aplicada al indicado tope, debido a que este collarín no está adosado a ningún elemento rígido que forme tope.

    Abstract: The opthalmic lens moulding process has a lens section (4) with a forward face (2) and a rear face. In the lens lifting step the lit face of the lens is swept by a luminous beam (22) whilst simultaneously raising on the optical receiver (24) the successive image points following the task settings (23) thus finding the lifting effect on the three dimensional edges.

    Abstract: The lens clamp comprises drive stop(s) (16a, 16b), each with a relatively non-deformable center (24a, 24b) surrounded by an outer collar (26a, 26b) of a semi-rigid and elastically deformable material bending to the shape of the lens (20). The collar is 1.5 mm thick and has a surface (28a, 28b) covered with a 1 - 2 mm layer (30) of a plastic or elastomer material making contact with the lens.

    Abstract: The invention relates to a method for carrying out the precise trimming of a lens ( 1 ), whereby the lens is held between two clamping plates ( 2, 3 ) in a given position and the grinding of the periphery of the lens ( 1 ) is controlled along a trajectory, the last programmed part of which corresponds to the form ( 8 ) desired for the lens. The method comprises a first scanning under weak clamping conditions of a number of points on one face of the lens with scanning of the coordinates of the points ( 8 ), forming the trace on said face of the mounting circle, a second scanning, with a significant level of clamping which corresponds to that used on trimming the lens of a second number of points on said face of the lens, an approximate mathematical representation of the face of the lens for each of the two clamping conditions, a calculation of the coordinates for the deformation of the contour of the lens on said face of the lens in the second clamping condition to correct the last programmed part of the grinding trajectory.

    Abstract: Device comprising in combination: elements for detecting ( 4 ) characteristics of a lens; elements for integrating characteristics representing a patient's morphology; a support ( 3 ) of the mobile lens along a predetermined trajectory between a first measuring position and a loading position; grinding elements ( 20 ); and elements forming a gripping and clamping clip ( 25 ) for transporting the lens from the loading position to the grinding position.

    Abstract: Method has the following steps: scanning of the profile using a planar light beam (F1-F8) arranged to cut the profile of the object being measured. The trace of the optical beams on the profile is determined using optical detectors means (31-33, 36) with an optical axis (35) forming an indicator angle that is constant and none zero with the light beams (F1-F8) at a series of positions around the profile. Each sampling point is chosen from one of the light beams in a pre-established fashion activated accordingly. An Independent claim is made for a device having at least two emitters for transmitting distinct light beams (F1-F8).
