Paper Abstract

The article describes modern production methods in manufacturing optical components. For the several operations there are specific requirements to be considered in machines and tooling. The author lays stress on centering and edging of optical lenses. However, when dealing with advances and efficiency in production technologies also the other operations for manufacturing optical components should be reviewed and therefore, these processes are described too. During the last few years special progress was made by the employment of diamond pellets in fining. Now one can assume that it became more or less a standard technology throughout the optical industry. It is similar with the development of suitable plastic materials for high speed polishing which have contributed to improve the processing of optical elements considerably. The latest advances offer further possibilities for substantial cost reduction in processing optical components. Generating and fining are done in a single step, called fine generating - ready for polishing. For centering the latest development of laser centering systems has made a great advance to improve efficiency of this process. The laser centering systems make it possible for the first time that even lenses with small centering angles can be worked cementless. It saves the costly operation of sticking on lenses for manual alignment to their optical axis.
