The radiation-selective absorber coating () has two barrier layers (), an IR-reflecting layer () arranged thereon, an absorption layer () arranged above the IR-reflecting () and an antireflection layer () over the absorption layer (). The absorber tube () is a steel tube () with the radiation-selective absorber coating () applied to the outside thereof. In the process of coating the absorber tube () a first oxide barrier layer () is applied to a steel tube by thermal oxidation; a second barrier layer () is then applied by physical gas phase deposition of silicon with supply of oxygen; the IR-reflecting layer () is then applied by gas phase deposition of gold, silver, platinum or copper; the absorption layer () is then applied by deposition of aluminum and molybdenum; and a final antireflection layer () is applied by deposition of silicon with supply of oxygen.
