In just one click, we measure thin-film thickness by analyzing how the film reflects light. Various dispersion equations of the finite-power-series type are used to obtain the best fit between transmittance measurements and calculations. You can count on our global team with seven offices around the world for immediate 24-hour film thickness support via online meetings and embedded diagnostics.
