About the Company

    LLC Abris-Optics is a domestic manufacturer of optical components, focused on quality and the advancement of Russian optics. Our company began its journey in the late 1990s. Based on market needs, in 2000 we organized a small enterprise and began receiving orders for the production of optical components.

    When designing the production line, only a minimal number of machines were available. On OS-320, 3ShP-320, and 4PD-200 machines we manufactured flat optics and gradually built a customer base. Later, we produced high-quality prisms, lenses, and mirrors.

    Thanks to the growing number of orders, we expanded our capacity: new modernized machines and highly qualified personnel appeared, which allowed us to improve product quality, production efficiency, and logistics. Initially, the production area was 200 square meters, and today the company’s working area is 1,200 square meters.

    Every year, the volume of components and the complexity of their manufacturing increased, with new types of parts introduced into production.
However, we realized that we were not carrying out the full cycle of all operations, and therefore decided to develop a vacuum coating section. For this purpose, vacuum units VU-1A and VU-2 were acquired, later upgraded with more powerful pumps and spectrovisors.

    From that moment, we began to carry out the full cycle of optical component processing – from blanks to vacuum deposition. An auxiliary section is the metalworking shop, where grinding and polishing tools, as well as various fixtures, are manufactured on a KLE-360 CNC lathe.

    Our production process starts with design documentation and discussions of technical details with the customer, as well as material selection.
Material procurement is carried out according to the customer’s requirements, with the option (upon request) of providing a technical certificate that confirms compliance of the glass with specific requirements and characteristics, which are especially important for optical applications. It may include information about the composition of the glass, optical properties, tolerances on dimensions and shape, as well as data on the manufacturer and standards used.

    We provide the manufacture of optical parts from materials listed in the catalogs: “Colorless Optical Glass” 13659-78, “Colored Optical Glass” 9411-91, “Quartz Optical Glass” 15130-86, covering the entire spectral range from ultraviolet to infrared. We also work with materials from foreign companies such as OXARA and Schott.

    In the blank preparation section, glass is cut, dimensions of different configurations and shapes are adjusted, and spheres are applied. Processing is carried out with abrasive grinding materials: diamond and electrocorundum.

    In the optical section, fine grinding and polishing of optical components are performed. Polirit is the main polishing abrasive used in the manufacture of glass parts. For bonding blanks to fixtures, the following materials are used: adhesive resin, adhesive paraffin, beeswax, shellac, gypsum, and optical contact.

    The working surface of the polishers is either technical woolen fabric (overcoat cloth) or polishing pitch. Materials are evaluated by the intensity of the process – the time during which the polisher retains the shape of the working surface given during its manufacture, and its ability to form a clean, defect-free polished surface.

     Grinding with diamond tools, regardless of the type of operation, represents the process of brittle fracture of glass, which occurs due to the scratching action of fixed grains.
Processing with polishing abrasives is the final stage of mechanical processing, resulting in surface irregularities smaller than the wavelength of the visible spectrum.

    The need to introduce the centering operation in the lens manufacturing process arose from errors in the positioning of blanks during the machining of refractive surfaces.
The centering operation consists of two sequential steps:

1. Aligning the optical axis with the spindle rotation axis and fixing this position.
2. Aligning the geometric axis of the lens with the optical processing path along the diameter.

    The accuracy of aligning the geometric axis of the lens with the optical one is determined by several factors, in particular: the values and signs of the radii of the lens surfaces; the mounting method, which determines the alignment accuracy of the optical axis with the spindle rotation axis; the accuracy of the spindle group of the machine; the accuracy of the technological base, which is provided by the centering chuck edge; and the qualification of the worker and setup operator.
