The M532® Raman microscope combines the capabilities of the Inspectr R532® Portable Raman Express Analyzer and the U300M microscope, adapting it for both transmission and reflection measurements. The wide functionality of the M532 microscope makes it possible to find and analyze individual particles with a size of 2-3 µm among many similar ones with similar physical and chemical properties, which opens up new research opportunities within the framework of a single Raman system. A spatial resolution of 1 µm and a spectral resolution of 4-6 cm-1 ensure excellent measurement accuracy and reproducibility. The compact design and portability of the instrument allow for high-quality and instant analysis of substances without sample preparation, which makes the M532 microscope an indispensable instrument for a wide range of studies. Equipped with a motorized slide (optional) with a step of 0.36 µm, the M532 microscope scans the surface of the sample, recognizes substances in multi-component heterogeneous mixtures and creates a graphical image of the intensities of Raman scattering characteristic lines at various points on the surface (2D mapping), which makes the M532 microscope the most advantageous in terms of price-quality ratio scanning Raman microscope in the world market.

At the Scientific Research Center of the Russian Academy of Sciences, the technology of acousto-optic filtration of optical radiation is used to create a wide class of optical devices that are successfully used, for example, in biomedicine to diagnose various diseases (including oncology), in agriculture to diagnose the condition of plants, during non-destructive testing of complex technical objects and in solving other tasks. Acousto-optics has a number of important advantages over other technologies for obtaining spectral information: - the ability to create imaging devices without spatial scanning, since the acousto-optic filter is a software-controlled tunable light filter; - the compact modular design allows the acousto-optic filter to be integrated into the optical circuit of most imaging devices, which expands their analytical capabilities; - spectrum scanning is carried out by means of an electrical signal, without mechanical scanning; - fast arbitrary spectral addressing causes high shooting speed and the absence of redundant information; - software management. The key element of the presented device – an acousto–optic filter - is being developed at the Scientific Research Center of the UP RAS on the basis of original calculation methods. The manufacture of acousto-optic filters, optical and mechanical components, as well as the assembly, tuning, and calibration of such devices is also carried out at the Scientific Research Center of the UP RAS.

The video camera and servos of the electrode holders built into the tripod are designed to automatically maintain the interelectrode gap during the evaporation of the sample by computer analysis in real time of the image of the arc discharge, as well as the initial setting of this gap relative to the optical axis. The electrode holders are cooled with water using a closed-cycle cooling unit.

The spectrometer is designed to determine the contents of elements in the range from Ca to U in substances in solid, powdery, dissolved states, as well as deposited on the surface or deposited on filters. The principle of operation of the spectrometer is based on irradiation of the sample with primary radiation from an X-ray tube, measurement of the intensity of secondary fluorescent radiation from the sample at wavelengths corresponding to the elements being determined, and subsequent calculation of the mass fraction of these elements according to a pre-constructed calibration characteristic, which is the dependence of the content of the element being determined on the measured intensity. Secondary fluorescent radiation is decomposed into a spectrum using a crystal analyzer. Due to this, the spectrometer has a high resolution, and therefore the ability to accurately analyze complex multicomponent substances.

A device for preparing metal samples for spectral analysis. For the preparation of metal samples, an emery cloth or paper with a given size and abrasive material is used. The rotation speed is 1500 revolutions per minute. A quick stop of the motor is provided by an automatic control unit. There is a version in a housing made of composite materials with two discs, each can have its own type of abrasive.

The product is designed for cleaning materials in a water environment with the addition of alkali at a temperature of up to 90 ° C by mixing in a laminated stream with maintaining the temperature of the liquid and automatic removal of the oil film. The tank is welded from a metal profile and is a rigid power structure. On the inside, U–shaped heating elements are installed to maintain the set temperature. Temperature control is performed by a digital device. The integrity of the heaters is monitored by a standard ammeter. The liquid level maintenance system ensures a constant level of liquid in the tank. When the liquid level in the tank decreases, the liquid is supplied automatically through the built-in valve (optional). To do this, a level sensor is installed in the tank. If the level drops unacceptably, the heating is turned off. A skimmer is installed to remove the oil film. The tank is equipped with a bubbling device. It can be equipped with a circulation pump.

The main advantage of a mobile spectrometer is the ability to measure the composition of alloys not only in the laboratory on specially prepared samples, but also directly in a workshop or warehouse without cutting the product or workpiece.
