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.

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 (102) is carried on a support (103) with spikes (106). Light arrives at the lens via two trajectories (112,113) from alternately switched light sources (S1,S2) using a semi-reflecting mirror and a Hartmann matrix mask (139) in one light path (112). An analytical unit (110) uses a matrix sensor or camera to determine lens characteristics and engravings respectively from the two trajectories

Abstract: The method of determining the cutting path of a groove is formed in the edge of an optical lens. The method involves gauging the position and thus the curvature of a rigid section (12) of the upper lens frame of the spectacles to allow matching of the contour of the groove in the upper edge of 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.

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).
