摘要： The invention pertains to the technology of manufacturing polymer elements including a method of manufacturing polymer microlenses with flat, spherical or aspherical refracting surfaces, said microlenses being solid or hollow and with either even or graded radial and (or) axial refractive index distribution. The polymer element is manufactured in the following way. A holder on which are secured one or more substrates (3) is placed in a tank containing a still buffer solution (2). A droplet of desired volume of an organic photosensitive composition is formed on the surface of a substrate with the aid of a dispensing unit, the photosensitive composition being not miscible with the buffer solution and of a density greater than that of the buffer solution, to form a stable element whose shape and conditions of formation are determined by the balance of forces acting on it. The substrates can have flat, curved or periodic surfaces, and can be hydrophilic or hydrophobic, specular, metallic, vitreous or of polymer, with heating or without. The droplet formed element is subjected to the action of activating radiation until it has completely solidified on the substrate to form the finished element. The walls of the tank containing the buffer solution are transparent to the activating radiation. After completion of the irradiation, the polymer elements (4) can be subjected to further thermo-polymerisation, removed from the substrate, washed, dried and heat-treated in order to minimise residual internal stresses. Anti-reflection and protective or photo-anisotropic, photochromic and other coatings can be applied to the surface of the element.
