PHE104 infrared spectroscopic ellipsometer is a unique infrared spectroscopic ellipsometry instrument based on monochromator-dispersion. It features highest accuracy, precision and is more economical compared to FT-IR spectrometer. PHE104 Infrared ellipsometry is a great new technology that proves invaluable to solid states and chemistry fields. It can be used on any substrate and offers high sensitivity on thin films down to surface passivation layers. Information on the optical constants,film thickness and chemical structures can be derived from the measurements.
