About us

The company was formed as an optical-computing group led by Oleg Kusch. Currently, the company engaged in the development of lighting devices for aviation and space, including:

  • Beacon-light-produced concentrated irradiation for artificial Earth satellite (designed light-optical system for docking module of the space station "Mir");
  • Optical systems for solar simulators;
  • Lighting fixtures for taxiways and landing lights for aviation

The company also has undertaken design of a range of fixtures for street lighting, illumination of industrial and office buildings, indoor lighting, etc. Projects have included installation of infrared heating and irradiation of goods with a given (usually uniform) temperature field.

Unique computer programs for calculation of specular optics of lighting devices were created in the 90s. Some of them have been demonstrated in a seminar at the International Commission on Illumination (CIE). The unique aspect of this software is inverse problem-solving, or the design of mirror surface shape when intensity distribution or efficiency criterion is prescribed.

The company's design team uses methods developed at Russian lighting engineering schools guided by the fundamental works by N. Boldyrev, A. Gershun, V. Komissarov, V. Fock. Recently, differential equations that describe the geometry of the mirror shape for a finite size light source have been obtained (Synthesis of specular reflectors for a finite size light source, A.A. Korobko, O.K. KuschLighting Research and Technology , 2004  — 36: 13-29). Geometrical and optical principles of design and calculation are set forth in the modern language of vector-and-matrix algebra. Thus a solid theoretical base of lighting-optical calculations was established, which is the main feature of our software.

Lead scientist Oleg Kusch has spent four decades working on the development of mathematical methods of flux concentration using optical devices. He defended a doctoral thesis: "Direct and inverse problems in the calculation of lighting devices, computer implementation." He also wrote the book "Computer-aided optical design of illuminating and irradiating devices".
