Fraunhofer Institute for Material and Beam Technology IWSMagnetron and ion sputtering as well as pulsed laser deposition are processes that we utilize to synthesize nanometer single and multilayer coatings. These coating systems fulfill highest demands with respect to thickness precision, smoothness, chemical purity, lateral uniformity and reproducibility. In addition to developing and manufacturing these coatings we also offer our experience in characterizing and modeling nanometer coating systems.
