Formation of gradient polymer lenses by non-stationary luminous flux

The diffusion processes in a layer of a photopolymerizable composition stimulated by non-stationary optical radiation causing the relocation of the neutral component concentration and formation of smooth distributions of the refractive index were investigated. By the method of computer simulation, it was shown that with the photopolymerization of such a multi-component medium, moving the illumination boundary along the polymerized layer makes it possible to create gradient polymer lenses with a parabolic and Gaussian profile of the refractive index. The experimental results on the optical formation of flat elements of gradient polymeric optics from the industrial oligomer OCM-2 with butanol as a neutral component are presented.
