To achieve the maximum sensitivity during measurements, a special prefix is used to the FT-801 Fourier spectrometer, which is an optical unit with a built-in highly sensitive MST detector cooled with liquid nitrogen. The set-top box is installed in the cuvette compartment of the spectrometer and connected to the corresponding external electrical port, the detector is turned on programmatically. In this case, the sensitivity of the method increases many times (up to 20) – depending on the type of standard uncooled detector in the spectrometer). The speed of recording spectra is also increasing. The operating time after filling the cryostat (200 ml capacity) with liquid nitrogen is at least 6 hours. Increasing the sensitivity of the spectrometer using a prefix with an MST detector may be required for many applications: in fiber spectroscopy, when recording emission spectra of low-power emitters, in trace gas analysis with high spectral resolution, when determining the presence of impurities in samples in ultra-low concentrations, when using multi-pass gas cuvettes, etc. In the picture: on the left in the cuvette compartment there is a capler with fiber from Art photonics GmbH, Berlin, Germany, on the right there is a prefix with an MST detector. Technical specifications The recommended number of scans when registering spectra is 16 Spectrum registration time at 50 scans (resolution 4 cm-1), sec 20 Cryostat capacity, 200 ml Working time after filling the cryostat, 6 hours Overall dimensions, mm 225×175×75 Weight, kg 1.45

Single- and multi-pass flask are used for qualitative and quantitative spectral analysis of gas mixtures. The use of multi-pass flask makes it possible to confidently detect extremely small concentrations of the components of the gas under study (less than ppm units). • Three types of flask are supplied: 1. single-pass, having a stroke length of 100 mm, with a glass body and windows made of ZnSe, KBr, NaCl 2. multi-pass, with a beam stroke length of up to several tens of meters 3. multi-pass, with a beam stroke length of up to several tens of meters, equipped with a heating system of the working chamber up to 200 ° C and a thermal controller Multi-pass cuvettes have a transparent working chamber made of quartz glass; mirrors with a gold (99.999) coating provide a reflection coefficient in the IR region of at least 98%; additionally, cuvettes can be equipped with pressure and temperature sensors, fittings for controlling gas flow, etc.

FT-801 IR Fourier spectrometers can additionally be equipped with a special optical set-top box that allows efficient use of light-guide systems. 4 types of light-guide probes allow measuring transmission and reflection spectra in solid, liquid and gaseous media Modern IR light guides have high intrinsic transmittance and sufficient mechanical strength, which makes it possible to transfer measurements from the laboratory directly to production - to control the flow of technological processes, check the quality of raw materials and finished products.

Designed for monitoring processes in reactors, vacuum chambers, gas pipelines, etc.

The main advantage of the PRIZ prefix is the possibility of obtaining well–defined spectra of micro-objects after giving them the shape of a thin layer on mirror-polished metal plates (in the mode of the so-called double passage, when radiation twice penetrates through the layer of matter, reflecting from the mirror-substrate). The presence of a visual control system with a built-in video camera significantly increases the information content when setting up and the reliability of the results obtained. With the help of the prefix, it is also possible to register the reflection spectra of bulk samples and solid objects of arbitrary geometry in native form, including pharmaceuticals in the form of tablets, powders and granules, polymer fragments, LCP, films deposited on the surface. Technical specifications Transmission in the operating range of the spectrum, % of the input signal at least 40 The recommended number of scans when registering spectra is 25 Spectrum registration time at 25 scans (resolution 4 cm-1), sec 30 Minimum initial dimensions of a solid sample, mm 0.2 × 0.2 The maximum area of the solid sample, mm 20X20X10 Variable focus range, mm 10 The diameter of the focus spot, mm 3 The angle of incidence of radiation (central beam) on the sample in the ZDO 45o mode Micro lens magnification / total magnification of the 4X visual channel Field of view of the optical system, mm 2 X 2.5 The resolution of the digital video camera is 640x480 Overall dimensions, mm 140×105×160 Weight, kg 1.16

NT-MDT Spectrum Instruments is an INTEGRA Nano IR–scattering scanning near‑field optical microscope (s-NSOM) designed for the infrared spectral range. The AFM probe is located in the focus of an optical system that directs the IR laser radiation to the sample and collects the optical response. The collected radiation is sent to the Michelson interferometer for optical analysis. The far-field component of the collected signal is suppressed by synchronous detection. The INTEGRA Nano IR system allows detecting the amplitude and phase of the near-field signal. The spatial resolution of the resulting reflection and absorption contrasts is approximately 10 nm and is determined only by the size of the tip of the probe.

It is used in the study of samples compressed into small-diameter tablets with KBr (the method is convenient for spectral analysis of powdery substances - the prefix allows you to work with small amounts of the sample using a manual press for the manufacture of tablets). • The diameter of the focus spot is less than 3 mm • Parabolic mirror optics are used in the design • Windows-substrates can be placed in the prefix after pasty, liquid substances or extracts are applied to them, followed by drying of the layers • Limited use – in the study of whole samples with dimensions less than 5 mm (preferably using a vertical-type microfocusing attachment)
