The System is designed for operating in the wavelength region of 1.4 to 4.2 µm, which is of prime importance as many industrial and anthropogenic pollutants of the atmosphere have absorption bands in this spectral range. The main fields of application includes control of the natural gas emission in the atmosphere, detection and identification of atmosphere pollution by industrial installations, mapping of aerosol clouds.

LT-PYRKAL is also an experienced producer of Hard and Soft Crystals, and possesses the appropriate research, production and control equipment to transform the grown crystals to Crystalline Optical Elements. The Company’s technicians are skilled in selecting and orienting crystals, cutting, lapping, polishing and coating them to perform up to laser standards. Two separate laboratories, equiped with X-Ray Orientation, Interferometer, Autocollimator and Spectrophotometers, are correspondingly dedicated to the treatment of Hard and Soft Crystals. Diamond turning capacity is available, while working with Sapphire, YAG, Quartz, Calcite, as well as with Fluorides -CaF2, BaF2, MgF2, LiF enables us to produce sizable Crystalline Optics, i.e. flats, prisms, lenses, windows and substrates.

Basalt Roving – Assembled basalt roving consists of several strands, drawn at the facility for the production of continuous basalt fiber and then assembled together, at assembling machines. The multifilament yarns of assembled roving are made of basalt scrap.

Basalt Reinforcing Mesh – Consists of bound filaments of basalt fiber, by adding polymer matrix. Basalt fiber has high durability and low thermal conductivity, and it is resistant to aggressive environments. Due to these qualities, basalt reinforcing mesh is more often applied in the construction instead of the metallic one. It does not require a special storage and it is resistant to precipitations and temperature changes. Basalt reinforcing mesh also reduces the thickness of the asphalt coating.

Machine tools for the production of rebars and reinforcing meshes – “Argel” closed joint stock company also offers machine tools for the production of composite rebars and reinforcing meshes.

Basalt Fiber/Chopped Strands - short extracts of basalt fiber, applied in the reinforcement of binding mixtures. Chopped strands are produced from roving, which is chopped at special choppers. Basalt fiber is resistant to chemicals. In comparison with metallic fiber, basalt fiber is resistant to corrosion, it increases the ductility of concrete structures and eliminates micro cracks.

Basalt Yarn Basalt yarn is manufactured by melting chopped basalt rocks in а furnace under the temperature of 15000C. The large amount of iron oxide in basalt rocks gives the stone typical dark color and increases the homogenization and the temperature of crystallization. Concerning the viscosity, basalt yarn is steeper than fiberglass yarn.

The problems at most railway tracks related to high-speed traffic and the increasing number of train pairs that result in the higher track occupancy rate, as well as cost analysis show the feasibility of using mobile systems as primary diagnostic tools. Over recent years TVEMA has made a major technical breakthrough in terms of development and manufacture of various components for NDT equipment installed on mobile diagnostic systems. This breakthrough has dramatically increased inspection reliability compared to manual diagnostic devices which ultimately made mobile diagnostic systems a number one choice.

SOKOL-2 track geometry assessment system is mounted on the bogie frame of any vehicle and intended for high-speed measurement of rail track geometry and rail head profiles with a contactless method at speeds up to 250 km/h.

The uniqueness of INTEGRAL diagnostic system for automatic condition assessment of railway infrastructure lies in the fact that it integrates in the framework of a single diagnostic train a multitude of various inspection subsystems providing measurement and processing of over 100 parameters of condition assessment for various facilities. Even the subsystems are mounted on different locations in the inspection vehicle their measurement results as well as all data acquired is localised to the true geographic- and track-coordinates.
