This paper will present recent developments in the field of microstructured plastic optics. Throughout the industry there is a steady push for improved precision and increased component efficiency as well as complexity. Discussed are different replication techniques and product enhancement capabilities, in particular coatings and nanostructures, such as top surface features of polymer optical components. Discussed are furthermore the properties, the efficiency, the application fields and the possible combinations of different AR-capabilities. We compare the periodical Motheye structure, the new random AR-structure PlasmAR (plasma based method) and the BBAR-coating (combination of chemical process and physical deposition process).
