Abstract

A procedure and an apparatus for the examination, in particular quality inspection, of optical components, in which an image is produced of the respective components to be examined, and defects on the imaged object are detected by image analysis, as well as the integration of this examination procedure into the production of the component. The optical components can be ophthalmic components such as spectacle lenses, contact lenses, intraocular lenses and the like. <IMAGE>
