Abstract: The template is mounted in the place of the ophthalmic lens on the grinder to be calibrated. It has the general shape of a disc being circular on a part of its periphery (22). There are locally two sharp points (23), circumscribed by the same circumference (C), which are angularly separated from each other by 90 degrees . In the smallest (A'1) of the two subtended angles at the centre (A'1,A'2) delimited by the sharp points the disc contour is concave. The circumference which circumscribes the two sharp points on its periphery then extends into its circular part (22A). The two sharp points result from the intersection of the disc circular part with a notch (22B) cut into its periphery.

Abstract: The method involves placing a template (2) corresponding to a lens to be obtained, in an axis. The template is placed to contact with a grinding stone (6) on another axis. A relative position of the axis is checked for achieving a discrete or continuous reading of the template. A shape of the template is determined by a calculation and the template is withdrawn. A raw-material is placed and processed. An independent claim is also included for a machine for manufacturing an ophthalmic lens.

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: 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: 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: 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 standard gauge comprises two jaws which extend parallel to each other, one being mobile w.r.t. to the other in the direction perpendicular to their length. A pair of spectacles is supported within the gauge so that one jaw contacts the bottom of the spectacles and one contacts the top edge. A feeler is mounted on a carriage in order to move over a base plate in order to take measurements of the contour of the spectacles to be examined. The appts. also includes a plate (50) with two projecting ribs (58) which lie parallel to each other. This serves as a support for the feeler gauge used in determining the contour of the spectacles.
