	The ellipsometer directly measures Ψ the amplitude ratio and Δ the phase difference of the polarization of light as it reflects off a sample surface. The data is collected at several incident angles and across a broad spectrum of wavelengths. Given these parameters the data is then fit to a set of mathematical models that is appropriate for the materials or multiple layers of materials. Once the other parameters are adjusted and the curves are properly fit, the desired property can be inferred.
