A small-sized IR Fourier spectrometer with integrated set-top boxes and two detectors, including a highly sensitive cooled MST. Operating modes: transmission and reflection, NIP, measurements using fiber-optic probes (possible versions with one or two pairs of built-in connectors). It is possible to connect an IR microscope, a telescope to register the spectra of external radiation. The spectrometer can be used as a portable one, and is used, among other things, for express monitoring of technological processes, quality control of liquids in tanks and pipelines, during in-line analyses of biological objects, remote gas analysis. The installation is designed to create high-quality images on various materials and provides the production of rubber cliche seals and stamps with a resolution of at least 1800 dpi. Description It was created on the basis of the innovative Shtrik platform, which is based on a unique control system, the hardware and software of which are entirely developed by specialists of our company. The installation is designed to create high-quality images on materials such as rubber, metal, plastic and provides the production of cliche seals and stamps with a resolution of at least 1800 dpi. The fiber laser used in the installation in combination with a system of galvanometric scanners ensures high quality engraving in static mode, does not require water cooling and special maintenance. When assembling the system, only tested and certified parts are used, which guarantees an especially long service life without additional investments. Features: A two-coordinate high-precision positioning system for samples, with the help of which the object table is moved along the X, Y axes. As a result of the positioning system and sequential engraving of image fragments, it is possible to process with high accuracy workpieces with dimensions up to 200 × 300 mm in automatic mode according to the processing program set by the operator; The algorithm of automatic layer-by-layer engraving using a high-precision mechanism for moving the scanning head along the Z-coordinate allows you to form highly detailed 3D images up to 5 mm deep in metal workpieces (steel, brass, aluminum, titanium, etc.); A long process of layer-by-layer engraving of deep 3D images (possibly tens of hours) is provided without operator involvement thanks to an automatic algorithm; The installation is equipped with a built-in system for removing combustion products from the laser radiation exposure zone, as a result of which, the absence of odors and protection of the scanning lens from the products of production is ensured, which is especially important when engraving rubber and plastics; The installation body completely covers the processing and propagation zones of laser radiation, and the engraving is performed according to the program set by the operator in automatic mode with the installation covers closed. This design of the installation allows it to be attributed to laser devices of hazard class 1.

It is designed for measurement by the method of disturbed total internal reflection with simultaneous visualization of a micro-object on an integrated and external monitor, as well as by the method of mirror-diffuse reflection with an angle of incidence of 45o at the upper location of the sample. The prefix in the mode of a single NIP is used to register absorption spectra: liquids of any degree of viscosity (solutions, suspensions, oils, etc.), including those with high chemical activity; solid objects of arbitrary shape, including samples with very high hardness (any polymers, fragments of paint coatings, etc.); powdery substances, including powders with very high hardness (drugs, pharmaceuticals, explosives, inorganic compounds); samples in the form of thin tapes; samples in the form of fibers. The maximum hardness and chemical resistance of the diamond significantly expand the possibilities of the method; there is no need for periodic replacement of the crystal. The set-top box allows you to register spectra without time–consuming sample preparation, and the presence of a visual inspection system of the studied surface with a high-quality video camera and a built-in high-definition mini-monitor increases efficiency when working with small samples - fragments of thin fibers, microparticles, etc. The built-in monitor has the functions of digital 10X zoom, inverting, etc. The image can be simultaneously displayed on the computer screen (using a USB interface) and then saved as a file. The removable flange provides a quick and convenient sample change and cleaning of the crystal surface. The design with a diamond element protruding above the base plane of the NPVO allows you to study samples with sufficiently large overall dimensions. The high quality and repeatability of the results is achieved due to the absence of the influence of the thickness of the substance layer on the shape of the spectrum and the intensity of the absorption bands. The sample retains its original physicochemical properties and, if necessary, can be further investigated by other methods. The universal attachment clamp is equipped with a precision lever mechanism for quickly lowering the tip and a micrometer screw that allows you to pre–set the optimal degree of pressure - this ensures quick sample change and repeatability of the results during measurements. For convenience when working with liquid and paste-like samples, as well as in the ZDO mode, it is possible to rotate the clamping console by 180o. The console is equipped with two replaceable tips – with a spherical working part and with a flat hinged head. The high hardness of the diamond allows the use of large clamping forces, which is the determining factor for obtaining high-quality spectra. A replacement table is used to register the specular and diffuse reflection spectra. The sample is located on the subject plane of the investigated surface downwards. The method is used to determine the spectral characteristics of optical parts, thin tapes on the surface, crystals, and other large solid objects of arbitrary shape and size.

It allows recording transmission spectra of objects with sizes from 500 microns (precious stones, optical parts, semiconductor materials). It is also 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 • The design uses parabolic mirror optics • The set-top box is equipped with a set of replaceable diaphragm holders for samples of different sizes • Windows-substrates made of IR-transparent materials can be placed in the holder after pasty, liquid substances or extracts are applied to them, followed by drying of the layers • The slide table has the possibility of smooth movement in vertical and horizontal directions to achieve the maximum signal level

The wide-range IR microscope of the MICRAN series, connected to the FT-801 and Infralum FT-801 Fourier spectrometers, is designed to study samples from 10 microns in size, including heterogeneous in composition.

It is intended for express analysis of various types of solid and liquid samples, including polymer particles, films and fibers, powdery substances, fragments of paint coatings, fuels and lubricants. The presence of an optical system for visual inspection of the surface under study with an increase of 75X ensures high efficiency when working with small samples – fragments of thin fibers, microparticles, etc. The universal clamp is equipped with a precision lever mechanism for quickly lowering the tip and a micrometer screw that allows you to pre–set the optimal degree of pressure - this ensures quick sample change and repeatability of the results during measurements.

A liquid flask with an adjustable layer thickness of the liquid under study is made in the form of an optical-mechanical attachment installed in the cuvette compartment of the FT-801 spectrometer. It contains focusing optics, removable holders of two windows-substrates with a diameter of 10 mm and two adjusting screws placed on the upper panel of the console housing and designed to set the required gap between the windows. A liquid of any degree of viscosity is pre-applied in the form of a small drop to the lower window and then, in the process of smooth convergence of the windows, evenly fills the gap between them. By rotating the adjusting screws and observing the transmission spectrum online, the user has the opportunity to set the desired thickness of the liquid layer, guided by the overall intensity of the entire spectrum or by the intensity of specific absorption bands. In the presence of calibration, which is easy to create using the ZaIR 3.5 program for several samples with a known concentration, the cuvette allows quantitative measurements. The flask is indispensable in the analysis of mixtures containing impurities in small proportions.
