Plant control and process monitoring using MOCCA^+® on industrial lines

Challenge    

The transfer of the EOSS^® system concept to industry aims to achieve a fully automated control system. The customer wanted operability from just one system, as a result of which all essential system functions had to be mapped in the MOCCA^+® (Modular Optical Coating Control Application) monitoring software, which is based on broadband transmission measurement.

Solution  

The MOCCA^+® software, developed at the IST over many years for the automated deposition of precision optical filters based on formulations, was adapted to work with the industrial EOSS^® system. This included functions for process planning, including the handling of substrates, as well as routines for automatic shutdown and restart in the event of power failures. The opportunities for learning from processes carried out with regard to deposition rates and material properties have been developed in such a way that they can already be used in a running process.

Added value    

MOCCA^+® offers a complete package for the production of optical layer stacks, from process planning and automated filter deposition to data analysis and archiving. It is now being used on various systems in the industrial environment and is designed in such a way that it can be transferred to other systems through adaptation of the interface.
