MEASUREMENT OF THE OPTICAL CONSTANT OF PAINTED POLYMERIC MATERIALS FOR EYEGLASS OPTICS Putilin Edvard Stepanovich, Elena Prunenko
By means of refractometry and ellipsometry method the measurements of the optical constants of superficially colored polymeric materials used in eyeglasses optics are carried out. It is shown that in a material after superficial coloring there are changes in absorption, parameter of refraction and refractive index dispersion.
CHOICE OF OPTIMUM ANTIREFLECTIVE COATING FOR APPLICATIONS TO SOLAR ENERGY Putilin Edvard Stepanovich, Nemkova Anastasia A
Efficiency calculation of various antireflective coatings for protective glasses of solar cell is performed on the basis of monocrystalline silicon. The calculation was made taking in account solar spectra and solar cell spectral sensitivity. It is shown that three-layer coating is the most effective in the case of normal angle of incidence and oblique incidence as well.
OPTICAL OBJECTIVE CONTROL PECULIARITIES FOR NANOSTRUCTURES FORMATION Kirillovsky Vladimir K., Yegor Gavrilov, Igor Bogdanov
For microelectronics development and obtaining the minimal size of a microchip element at the 10 nm level it is necessary to work out control tools of extended precision. It is shown that the main task to support the production of projection lens elements is creation of control tools for correlation between control and operating wavelengths in a deep vacuum-ultraviolet range. The interferometer for wave aberrations research is described.

DIELECTRIC PARTICLES TRAPPING AND DEFORMATION BY THE GRADIENT FORCES OF THE LIGHT PRESSURE Vladimir Tarlykov, Andrey Nelepets
The mechanical stress distribution on the surface of dielectric microparticles under the action of light illumination is theoretically and numerically studied. Light reflection and refraction cause momentum change and mechanical forces emergence. These forces may be used for trapping and deformation of dielectric microparticles ensembles. Two schemes of controlled particles deformation by the gradient forces of the light pressure are proposed.
MODEL CONSTRUCTION OF SPINODAL PHASE DECOMPOSITION AT HYPERBOLIC DIFFUSION Popov Igor Yu , Anna Bormotaeva
The mathematical description of the process of spinodal decomposition in high speed diffusion has been made on the basis of hyperbolic-type equation. This model is in agreement with the theory of Cahn and Hilliard at relatively small velocity mass transfer of components. The numerical research has been done that revealed changes of domain’s boundaries caused by appearing of new phases.

Fluorophosphates glasses are one of the representatives of the class of fluoride glasses and combine properties, which make their using possible in fiber optics and laser optics. Thus, the main idea of our work was to study doped ion effect glass structure of Ba(PO3)2 – MgCaSrBaAl2F14 composition co-doped by europium and terbium ions. Received data analysis shows that glass structure dramatically depends on doped ion concentration.
