Spectroscopic Ellipsometer is widely used for thin film analysis and measurement. It is an accurate and versatile technique for research on semiconductors, dielectrics, polymers, metals, multi-layers, and so on. Variable Angle Spectroscopic Ellipsometer (VASE) uses Rotating Analyzer Ellipsometry technique to characterize thin film samples. And it uses high speed CCD array detection to collect the entire spectrum. It measures films with nanometer thicknesses up to tens of microns and also measures the optical properties of transparent and absorbing materials. It accurately measures optical constants like refractive index, film thickness and extinction coefficient. It combines high accuracy and precision with a wide spectral range from 193 to 2500 nm. Variable wavelengths and angles of incidence allow for flexible measurement capabilities.
