The flexible and efficient production of precise optical free-form surfaces requires advanced kinematic operating principles. Due to the complex surface geometries, polishing processes with point or linear contact are used. These generally result in

Due to the increasing demands and complexity of optical glass components to be processed in the future, advanced technologies and precision machining methods will be required in order to produce high-quality optics economically. The polyjet process e

In many conventional optical manufacturing processes, lapping is still a standard method to provide polishable surfaces. With the increasing use of CNC technology, efforts are being made to substitute the lapping process in the process chain. The pap

While acoustic emissions are a method for e. g. the monitoring of bridges or for the assessment of the integrity of tanks, we wanted to investigate them for a further field of application. We tested AEs for the monitoring and assessment of a high-qua

Scratches and microdefects on glass surfaces significantly impair the optical and mechanical properties of optical components. They already occur during mechanical processing (shaping) and have to be removed in several specific processing steps. A pr

The laser beam polishing for glass and plastics is a purely thermal process and melts the ground or lapped structures to a depth of limited extent. This results in a smoothing of the surface, whereby the 1st - 4th order shape deviations can be correc

In the digital age it has become a fundamental issue to monitor and control process parameters continuously and automatically. The monitoring of critical process parameters enables better quality at lower production costs and higher yields. In order

In previous publications the inhomogeneous pressure transfer through the polishing tool onto a glass surface could be shown. This experiment shows polishing trials with different polishing materials and the differences in the homogeneity of the press
