Key features & benefits
Measurement Flexibility
The SENTECH SENDIRA spectroscopic ellipsometer measures thin film thickness, refractive index, extinction coefficient, and related properties of bulk materials, single layers, and multi-layer stacks. The tool can be used for layers below covering layers that are non-transparent in the visible range making them accessible for measurement. The composition of materials and orientation of larger molecule groups and chains can be analysed.
Ellipsometric vibrational spectroscopy
The composition of thin layers is analysed using the absorption bands of molecular vibrational modes in the infrared spectrum. Also, the carrier concentration can be measured with this FTIR spectroscopic ellipsometer.
Fully applicable FTIR
For the commercial FTIR iS50 from the Thermo Fisher Scientific spectrometer, infrared ellipsometer optics is attached. It is available for general vibrational spectroscopy as well.
The SENTECH SENDIRA is specially designed for infrared (FTIR). The compact tabletop 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).
Precise measurement and accurate results
The SENTECH SENDIRA is focused on the vibrational spectroscopic analysis of thin layers. Applications range from dielectric films, TCOs, and semiconductors to organic layers. The SENDIRA is operated by SpectraRay/4 software. FTIR software is provided additionally.
