Abstract

Optical coatings with enhanced roughness offer promising prospects for ultra-hydrophobic transparent surfaces with controlled scatter losses. Our coating design approach is based on roughness characterization by power spectral density (PSD) functions as a tool to describe both the wetting behavior and scattering. For the design of architectural glass coatings, the definition of scatter thresholds is necessary. These thresholds can be determined from investigations that link visual inspection and total scatter (TS) measurements. Experiments with rough oxide layers yielded surfaces with a high water contact angle.
