PRODUCTION

The production of «FOCUS Inc.» is the output of products in the following main areas:

  • Manufacturing of optical components

    The production of optical components is the main activity of the enterprise. In the manufacture of optical components, optical materials of both Russian and foreign production are used. These are various optical glasses, some crystals, metals. The fundamental document for the manufacture of optical components is the design documentation provided by the Customer or issued by «FOCUS Inc.» on the basis of the terms of reference or specification of the Customer.

    To select Russian-made optical materials, «FOCUS Inc.» specialists are primarily guided by the following standards in force in the Russian Federation:


    In addition to domestic materials for the manufacture of optical components, materials from foreign manufacturers are used: Schott, Ohara, Sumita, Hoya, etc. To do this, the company's specialists are guided by the catalogue of listed companies and the standards of the relevant states (MIL, DIN, etc.).

    A short list of optical components manufactured by «FOCUS Inc.»:

    • spherical lenses (plano-convex, plano-concave, biconvex, biconcave, posi tive and negative menisci)
    • spherical glue lenses (plano-convex, plano-concave, biconvex, biconcave, positive and negative menisci)
    • mirrors (flat, spherical convex, spherical concave, cylindrical convex and concave)
    • protective glasses
    • flat plates
    • interferometric plates
    • optical windows
    • precision prisms and prism gluings (rectangular, equilateral, Littrov, Dove prisms, pentaprisms, roof prisms, etc.)
    • substrates for mirrors and diffraction gratings
    • color and interference filters
    • neutral filters
    • ball lenses
    • microlenses
    • cylindrical lenses (plano-convex, plano-concave, biconvex, biconcave, positive and negative menisci)

  • development and production of optical systems (mainly – lenses)

    Over the 30 years of its existence, «FOCUS Inc.» has been manufacturing various optical systems. As an example demonstrating the level of qualification of the company's specialists, below are the optical schemes of lenses designed and manufactured by specialists:


  • Production of optical coatings used to improve or expand the functions of optical components

    The manufacture of optical coatings for optical components is carried out in accordance with OST 3-1901-95. «Coatings of optical parts. Types, basic parameters and methods of control».


  • Production of optical resins for the production of optical components

    The production of optical resins is carried out in accordance with the following regulatory documents:

    • RTM 3-72-70. «Adhesive and polishing resins used in the processing of optical parts. Classification, recipe, manufacturing technology»
    • Technological instruction. Resins for optical production. Ю-25.048.00008
