The unique features of the spectrometer are very low requirements of the sample (several milligrams are usually enough to carry out the measurement) and capability to perform the measurements in wide range of temperatures (from room temperature up to 1200 °C). The spectral range is from 45 to approximately 4000 inverse centimeters, with resolution up to 3 inverse centimeters. There are two excitation lasers – green and near infrared – which can be easily switched during the measurement. The accompanying software allows complex processing: spectra averaging, zero line adjusting, Fourier analysis and so forth.

• Complex for sample preparation includes automatic cutting machine of high precision, as well as single-disk grinding and polishing machine for high-efficiency and fast processing and preparation of samples for studies (optical and atomic force microscopy, dilatometry, mechanical studies on the nanometer scale).
