FIELD: optics. ^ SUBSTANCE: on a non-light sensitive glass, a surface light-sensitive layer is put, in which, through exposing to UV-radiation, corresponding to the calculated gradient, and weak transmission of the glass material of the optical element, a varying concentration crystalline phase is formed, which is used as a crystalline mask with a varying diffusion transparency, through which ion exchange can be achieved from molten salts. ^ EFFECT: obtaining a calculated gradient of refraction coefficient for correction of aberration in glass. ^ 3 dwg |
