Production for the future FED (Flexible Electronic Devices) and security markets must begin to take advantage of roll to roll coating. To guarantee high productivity and high quality, inline control of layer properties are required. This paper presents spectrometric and new ellipsometric inline measuring methods developed for a variety of different vacuum coating systems. Selected applications include the preparation of copy protect layers employing color shift and high quality diffusion barrier layers for FED in both Solar and OLED.
