A laser ellipsometer is a single-wavelength optical instrument used to measure precisely the thickness of coatings or characterize the optical properties of a sample as a function of its refractive index.
Laser ellipsometers are used in the optical and microelectronic industries and in the fabrication of photovoltaic cells.
A single-wavelength ellipsometer uses a laser as a monochromatic light source. The polarization of the light beam will be changed as it is reflected from the plane surface under analysis. The instrument measures this change and compares the result to a database to determine the characteristics under study.
