Abstract
A method and a device are disclosed for follow-up treatment of the contour of the surface of at least one optical lens, in particular a microlens which is made of glass or a glass-type material and which has a convex lens surface delimited by a circumferential line abutting on a plane section surrounding the circumferential line and which has a lens underside facing the convex lens surface. Along the circumferential line of the optical lens on the plane section is placed a device perfectly matching the circumferential line and at least laterally bordering the convex lens surface, the optical lens is heated to a temperature of at least the transformation temperature of glass or glass-type material, pressure equalization prevails between the convex lens surface and the lens underside, after a certain period of time, during which the optical lens undergoes the temperature treatment and subsequent cooling below the transformation temperature, the device is removed from the optical lens.
