Abstract
A reflector for helio-thermal systems may include a metallic carrier plate and a reflective coating that is applied to the carrier plate and is constructed from at least one metallic reflective layer and at least one protective layer applied to the reflective layer. Such reflectors have high reflective capabilities, are robust in relation to mechanical stress, and can be manufactured cost effectively. Such reflectors are also lightweight and dimensionally stable due to the fact that the carrier plate may be formed from a sandwich plate having at least one nonmetallic intermediate layer disposed between an upper and lower metallic cover plate. The upper cover plate may have a smoothed surface to which the reflective layer can be applied. The smoothed surface prior to the reflective layer being applied may have an arithmetic mean surface parameter Ra of less than 0.03 μm. Methods for manufacturing such reflectors are also disclosed.
