Abstract
The concept of component-level performance characterization of optical elements is introduced as an example of optimizing product quality using "Industrie 4.0" approach. In this context, "product" denominates an assembly of components, usually provided by different suppliers. Quality of such a product will be predicted by modelling according to measured properties of real components. This is demonstrated on manufacturing of marine signal lights, composed of LED source, secondary optical element (SOE), housing and electronics. Molded freeform SOE suffer from irregularities on surface, but also from internal properties like local differences in refractive index. By determining SOE´s angle mapping function, we derive a performance prediction of the signal light. Experimental results clearly show a good correlation between model predictions and signal light´s behavior.
