Spectroscopic ellipsometers SENTECH Instruments GmbH

SENpro (low budget)

The SENpro ellipsometer is the smart solution to spectroscopic ellipsometry applications. It features a goniometer with angles of incidence in 5 °-steps. Easy operation, rapid measurement, and intuitive data analysis are combined in a cost-effective design for measuring thickness and optical constants of single films and multilayer stacks.


The SENresearch 4.0 spectroscopic ellipsometer covers the widest spectral range from 190 nm (deep UV) to 3500 nm (NIR). High spectral resolution is offered to analyse even thick films up to 200 µm thickness using FTIR ellipsometry.


Vibrational spectroscopy is featured by the FTIR ellipsometer SENDIRA. Measuring the absorption bands of molecular vibrational modes in the infrared, the orientation of long molecule chains and the composition of thin films are analysed. Infrared spectroscopic ellipsometry is suited for measuring charge carrier concentration of conducting films.


Automated spectroscopic ellipsometry by SENDURO® comprises recipe based quick data analysis within a few seconds. The ellipsometer is designed for easy operation: Placing the sample, automatic sample alignment, automated measurement and analysis, result. Using spectroscopic ellipsometry in the automatic mode is perfectly suited for routine applications in quality control and R&D.
