Abstract
A method and an apparatus serve for visualizing a signature mark on a spectacle lens. In order to identify the signature mark, an illumination light beam is directed onto the spectacle lens, which impinges on the spectacle lens, after impinging on the spectacle lens is reflected at a retroreflector, impinges once again on the spectacle lens, and finally is passed as an observation light beam to a camera. A reflection region of the illumination light beam on the reflector is varied by means of a moved first optical element.
