Modern spectral optical instruments developed in scientific technological center of unique instrumentation of Russian Academy of Sciences

Review of modern spectral instruments, which are developed in STC UI RAS, is presented. They comprise Fourier-spectrometers and spectrometers based on acousto-optical tunable filters (AOTF): hyperspectrometers, stereo-spectrometers, endoscopic imaging spectrometers, as well as some other devices applicable to spectral optical investigations like lasers. All the instruments are classified in accordance with basic features and characteristics. They includes optical passive and active elements, devices and specialized systems, which totally cover spectral range from 0.25 µm to 3.2 mm and operates with optical and microwave radiation as well as with terahertz plasmon-polaritons. They implement various spectroscopic techniques: emission, absorption, fluorescent, Raman, differential, multi-wavelengths, correlation and modulation spectroscopy. These devices can be exploited in out-of-lab environment and are promising for industrial control, biomedical researches, monitoring of environments, material analyses, including high pressure and high temperature investigations.
