||The ellipsometer is able to measure the refractive index and the thickness of semi-transparent thin films. It can be used to measure layers as thin as 1 nm up to layers which are one micron thick. Applications include the accurate thickness measurement of thin films, the identification of materials and thin layers and the characterization of surfaces.
