GRADANS WHICH HAVE AXIAL FORM OF GRADED REFRACTIVE INDEX
Elements of producing technology and meso-and microscopic structure of domestically produced gradans-compilers with axial shape of refractive index, as well as fractography samples at external perturbations are introduced. This work is among the first in Soviet literature concerning the influence of technological structure inhomogeneities gradans that adversely affect the level of physical, chemical and mechanical properties of gradient optics samples. Types of mesostructural, surface and subsurface defects on difference- and micro-structure gradans affecting the increase in aperture ray scattering and reduced transmittance glass for samples with flat working surfaces have been observed experimentally.
