Introduction,urfaces and internal interfaces. Despite of material properties, geometrical parameters like film thickness are therefore essential for adequate description of their properties. For accurate and reproducible adjustment of material and geometrical film properties, numerous film deposition and growth

Basic Knowledge on Optical Constantsnd discussed. Emphasis is placed on amorphous coating materials. Consideration is given to the requirement of Kramers–Kronig-consistency of the dispersion behaviour. The basic optical properties of material mixtures are also introduced.

Plane Interfacesptically homogeneous and isotropic materials. Real films however may show certain surface roughness, as well as inhomogeneity and anisotropy. The impact of these effects may require introducing correction terms to Fresnel’s equations. Concerning the impact of surface roughness, so the latter needs t

Experimental Determination of Thin Film Optical Constantsstrates from ex situ transmission and reflection measurements are discussed in full detail. In situ transmission measurements and shift measurements complete the treatment. Examples include dielectric coatings, transparent conductive oxides, and metal coatings.

Oxide Coatings: Porous and Dense Filmsd. Practical examples focus on oxide coatings; comprehensive experimental material is presented for titanium dioxide, niobium pentoxide, tantalum pentoxide, zirconium dioxide, hafnium dioxide, aluminum oxide, and silicon dioxide films produced by means of different PVD techniques.
