Method for operating a coating system for producing layer systems

A method for operating a coating system in a self-controlled and feedback mode for producing layer systems, comprising:

• (i) coating a substrate with a layer system that includes a plurality of layers in a coating facility to obtain a finished spectacle lens, wherein the substrate is a transparent plastic material for a spectacle lens;
• (ii) determining a spectral actual measuring plot for the layer system of the finished spectacle lens in an optical measuring system;
• (iii) loading a target data set with a design of the completed coating of the layer system from a design database and the actual measuring plot into a simulation computer;
• (iv) determining an actual data set by fitting a simulation target measuring plot to the actual measuring plot in the simulation computer by varying physical individual layer thicknesses of the target data set until the actual measuring plot has been met;
• (v) determining actual layer parameters as computed actual layer parameters from the simulation target measuring plot by simulation of the layer system using the actual data set in the simulation computer, wherein the determined actual layer parameters include reflection values in wavelength ranges or at angles of incidence outside of the values obtained from the actual measuring plot;
• (vi) outputting the actual data set and the computed actual layer parameters at least to a decision system in the form of a processor or as a process on a control computer of the coating system and to a filing database;
• (vii) after the actual data set and the computed actual layer parameters are obtained from the simulation computer and output to the decision system, loading approval criteria and quality requirement data into the decision system, wherein the approval criteria and quality requirement data are from a criteria database, the approval criteria comprises permissible and/or nonpermissible layer parameters, from which the quality requirement data are derived, and the quality requirement data comprise tolerance values for the target data set;
• and comparing the actual data set, the computed actual layer parameters, and the quality requirement data;
• and
• (viii) deciding on an approval of the layer system of the finished spectacle lens in the decision system on the basis of a comparison of at least the actual data set, the computed actual layer parameters, and the quality requirement data.
