SENDIRA

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.

Ellipsometric vibrational spectroscopy

The composition of thin layers is analyzed using theabsorption bands of molecular vibrational modes in the infrared spectrum. Also the carrier concentration can be measured with this FTIR spectroscopic ellipsometer.

Fully applicable FTIR

To the commercial FTIR spectrometer an infrared ellipsometer optics is attached. It is available for general vibrational spectroscopy as well.

The spectroscopic ellipsometer SENDIRA measures thin film thickness, refractive index, extinction coefficient, and related properties of bulk materials, single layers, and multi-layer stacks. Especially layers below covering layers that are non-transparent in the visible range are now accessible for measurement. Composition of materials and orientation of larger molecule groups and chains can be analyzed.

The SENTECH ellipsometer SENDIRA is especially designed for the infrared (FTIR). The compact table top instrument comprises the purged ellipsometer optics, computer controlled goniometer, horizontal sample platform, auto-collimating telescope, commercial FTIR, and DTGS or MCT detector. The FTIR provides excellent precision and high resolution in the spectral range from 400 cm-1 to 6,000 cm-1 (1.7 µm – 25 µm).

The spectroscopic ellipsometer SENDIRA is focused on the vibrational spectroscopic analysis of thin layers.Applications range from dielectric film, TCOs, semiconductors to organic layers. The SENDIRA is operated bySpectraRay/3 software. FTIR software is provided additionally.
