Lytkarino — 30% of world production of optics for telescopes

At 16 kilometers from Moscow housed a unique company, part of the holding "Schwabe" — Lytkarinsky Optical Glass Factory (JSC "LZOS"). That’s it for optics specialists do observatories from all over the world. According to the main optics company Magomed Abdulkadyrova here produces about 30% of the total world market of large optics. Production capacity LZOS possible to produce high-precision optics sizes up to 6 meters.

On Lytkarino Optical glass optics for ordering group Faulkes Telescope Project of the American, European Southern Observatory, a large multipurpose spectroscope to observe large areas of the sky, which is located in China, as well as a number of other similar research facilities. Not to mention that the main mirror penalty Greater South African telescope (one of the largest in the world), is composed of 91 pyroceramics optical element made at LZOS. The unique properties of the glass-ceramic glass ceramic material — low density (it is lighter than aluminum), high mechanical strength, hardness, heat resistance, heat resistance, chemical resistance, combined with most of the positive properties of which are of glass, making it ideal for production of various optical elements in the including cosmic lenses. It should be noted that the production of glass-ceramic technology owned by only two companies in the world and one of them — the Russian holding "Schwabe".

Russia is among the three largest global suppliers of optical glass, along with Germany and Japan. On Lytkarino know of more than 300 recipes for cooking it. In addition, LZOS the only company in the world that combines all stages of production, from the melting of glass to create a ready-made optical devices. The plant produces: large lenticular lenses astrozerkala, viewing windows for protection against radiation, windows, vision devices, night vision devices for military equipment and much more. With the assistance of the company "Carl Zeiss Jena" (Germany) were won international tenders for the manufacture and supply of primary mirror diameter of 2.6 meters for the project VST (Italy) and the primary mirror diameter of 2.3 meters for the National Observatory of Athens (Greece ).

When Lytkarino Optical Glass won the competition for the production of mirrors VST c asphericity of 100 microns, many thought it was a joke before these characteristics did not give any manufacturer in the world. However, this has not stopped the company to cope with the problem and accurately fulfill all the conditions of the contract. A few years later took up the project LZOS VISTA (Visible and Infrared Survey Telescope for Astronomy) with aspheric much higher — in 1000 microns!

All the preparatory work prior to the processing of mirrors took about one and a half years. Engineers had to perform a huge number of calculations — the archive VISTA has a volume of about 3 cubic meters!

The mirrors were manufactured and delivered to the customer. Now they belong to the European Southern Observatory. Both work in the infrared spectrum, "tandem" with "our" as telescope mirrors VST, which are designed for operation in the visible spectrum. However, you can also mirror M1 "work" in the visible region of the spectrum — the opportunity inherent in it LZOS engineers.

VISTA infrared telescope is the latest addition to the array of telescopes at ESO’s Paranal Observatory. The telescope VISTA — Wide-largest telescope in the world, which is used for observations of the sky at infrared wavelengths. With the help of VISTA, the astronomers were able to create an image of the sky with the widest of all in existence today, the field of view of the infrared images. Each barely visible point on it is a galaxy that is composed of billions of stars. After processing the received information that allowed scientists to identify more than a dozen of thousands of previously unknown, mostly very distant galaxies whose light reaches us from the era of the early universe, when her age was less than a billion years.

JSC "Lytkarinsky Optical Glass Factory" is a unique multi-enterprise Optical Industry of the Russian Federation, is one of the companies providing the country’s defense. The company has reached world-class quality products and currently is a recognized leader in the manufacture of optical materials for various fields of science and technology in the Russian Federation.
LZOS of a strong scientific and technical center for the development of new products, technologies, and three large specialized production:

— manufacture of optical materials including optical glass cooking, making preforms and optical fiber elements;

— workpieces and fabricated optical products such as large-size optics including lenses and mirrors, ground and space-based astronomical purposes, as well as optical components for various applications;

— production of opto-mechanical and opto-electronic devices for various purposes, as for the masses, and specialized in consultation with the customer.

  • Low tide in the glass block

Many years of experience in the production and effective cooperation with the industry institute "VSC GOI. Vavilov" allowed LZOS master the production of more than 250 brands of colored and colorless optical glass. The plant supplies its products to enterprises as Russia and the CIS, and in Europe, America and Asia. The high quality of glass produced is provided proven advanced technology, using high-purity raw materials and valuation allowances for basic parameters of optical glass.

A significant share of the production of optical glass with special properties:
— laser glass and phosphate-silicate with varying concentrations of activators to create a solid-state lasers, which are used in special rangefinders, sights and scientific research;
— anoxic chalcogenide glass or IR region;
— glass-ceramic material — glass ceramics with a near-zero coefficient of thermal expansion, and used to make buildings with angstrom precision gyroscopes for guidance systems and mirrors for astronomical telescopes and space-based sensors;
— flexible fiber optic bundles to transmit light and images in endoscopes, rigid fiber-optic plate (twisters) used in the electron-optical converters (EOC) 2 + and 3 generations of night vision goggles and scopes.
