Brief description：A spectroscopic ellipsometer is an effective technique for characterizing thin films using spectroscopic ellipsometry. Spectroscopic ellipsometry is a surface-sensitive, non-destructive, and non-invasive optical technique widely used for thin layers and surface features. It works by analyzing changes in the polarization state of linearly polarized light after it reflects off a thin film sample, and model fitting is used to determine properties like thickness and optical constants. Depending on the thin film material, the measurable thickness can range from a few angstroms to tens of microns. An ellipsometer can characterize a variety of thin film properties, such as film thickness, optical properties (n, k), optical bandgap, interface and roughness thickness, film composition, and layer uniformity, among others.
Industry Applications：Characterization of optical film coating thickness and performance.
