Figure 1 From Total Angle Resolved Scattering Characterization For At fraunhofer iof, angle resolved light scattering techniques are developed and used for the characterization of optical surfaces, coatings, and components for a broad range of applications. examples will be shown, such as the analysis of ultra low optical losses of an ultra high reflecting mirror. Based on several examples we demonstrate the potential of light scattering characterization during the fabrication process up to even in situ coating inspection.
Angle Resolved Characterization Of Semiconductor Plasmonic Gratings In Angle resolved light scattering is used to analyze sub micron defects in coatings to improve performance and stability of optical components for high power laser applications. Surface and thin film characterization using angle resolved light scattering: from roughness and defect analysis to in situ coating inspection. Light scattering measurement and analysis consti tute a powerful approach to the characterization of surfaces and thin film coatings. a number of tools for the measurement of the total and angle resolved scattering at various wavelengths have been devel oped at fraunhofer iof. For single surfaces, light scattering techniques have become a powerful tool for the characterization of surface roughness. for thin film coatings, however, solving the inverse scattering problem seemed to be impossible because of the large number of parameters involved.

Although the samples studied in this work are flat, the technique can in principle be extended not only to study curved surfaces frequently encountered in transport industries but also to characterize different thin film coatings designed for reduced friction and enhanced resistance.
