摘要：
Highly selective absorber coatings are necessary for the effective operation of state-of-the-art solar thermal collectors. The thin film gradient optical coating with its spectrally selective characteristics achieves high solar absorptance combined with low thermal emittance. Such complex multi-layer systems are produced in modular vacuum coating processes. Industrial air-to-air coating lines allow the continuous coating of metal bands in a pass-through process and provide absorber coatings which meet highest demands for efficiency, durability and esthetics. © 2012 WILEY-VCH Verlag GmbH & Co.
