Both thick and thin films can be measured using the SENTECH SENresearch 4.0 spectroscopic ellipsometer. With a spectral range of 190nm in the DUV up to 3,500nm in the NIR the SENresearch 4.0 has one of the widest spectral ranges available in one instrument.

Use of FTIR in the near infrared range allows for a high signal to noise ratio and high spectral resolution. FTIR measurement offers faster measurement of thick films compared to other techniques.

We offer a free sample measurement and demonstration service to customers considering a purchase so please contact us with information about your application.

SENTECH Instruments of Berlin have been manufacturing tools for thin film metrology and processing since 1990. They are a growing company with a reputation for high quality reliable equipment and excellent service.
