TL;DR: Two-dimensional power spectral density functions were calculated from the digitized measurement data, and roughnesses were obtained by integrating areas under the PSD curves between fixed upper and lower band limits.

TL;DR: In this article, the authors calculate the band-limited relevant roughness from surface metrology data, then present parametric plots of the TIS for optical surfaces with arbitrary roughness, surface correlation widths, and incident angles.

TL;DR: It is demonstrated that the approximate scatter models yield surprisingly accurate results and at the same time provide insight into light scattering phenomena.

TL;DR: The IBS process achieves the best homogeneity and the lowest surface roughness values of the processes compared in the joint experiment, and in contrast to MgF2 boat and e-beam evaporated coatings, IBS coatings exhibit high compressive stress of as much as 910 MPa.

TL;DR: A simplified model is presented that introduces two parameters that describes optical thickness deviations from the perfect design, and the roughness evolution inside the coating according to a power law, and is used to investigate structural and alteration effects of HR coatings for 193 nm, as well as laser-induced degradation effects in Rugate filters for 355 nm.
