This setup allows for the precise measurement of the ellipsometric angles, Psi (Ψ) and Delta (Δ), which are directly related to the optical properties of the material being studied. Measurement ...

Ellipsometric Porosimetry (EP) measures the alterations in optical properties and thickness of porous thin films by spectroscopic ellipsometry (SE) during an adsorption cycle of an organic solvent.

During an adsorption cycle of an organic solvent, Ellipsometric Porosimetry (EP) measures the changes in optical properties and thickness of porous thin films by spectroscopic ellipsometry (SE). As ...

Within the field of quality control our referenced spectroscopic ellipsometer (RSE) represents a tool combining high speed (200 spectra per second) with the accuracy of an ellipsometric measurement.

Ellipsometric measurements: blue tone lines define ψ spectra, and red tone lines define Δ spectra. The peak in ψ and the 180° jump in the Δ spectrum appear at λ 0 =1.55 µm for all θ angles ...
