    • The invention pertains to the technology of manufacturing polymer globules. The aim of the invention is to simplify the industrial process and improve the quality of the polymer globules produced. To that end, a defined quantity of an organic photosensitive composition is introduced with the aid of a dispenser into a tank (1) containing a buffer solution (2), the density of the photosensitive composition being equal to that of the buffer solution, thus producing spherical bodies (3) suspended in the solution. The walls of the tank (1) and the buffer solution (2) are transparent to the activating radiation. A globule (3) suspended in the still buffer solution is exposed to external activating radiation (4) which evenly illuminates it from all sides until complete photosolidification occurs. Following irradiation, the solid globules are washed in running distilled water and alcohol and are dried in a vacuum drying cabinet in which the temperature rises slowly to a level not exceeding the glass transition temperature of the solidified composition. The globules are kept at this temperature for a time and subsequently allowed to cool slowly to room temperature with the aim of minimising residual inner stresses. The proposed method facilitates the production of aspherical, including graded, lenses, with an axial and a radial refractive index gradient, as well as hollow spherical and aspherical microlenses.
    • 本发明涉及制造聚合物球的技术。 本发明的目的是简化工业过程并提高生产的聚合物球的质量。 为此,借助于分配器将限定量的有机光敏组合物引入到含有缓冲溶液(2)的罐(1)中,感光组合物的密度等于缓冲溶液的密度,因此 产生悬浮在溶液中的球体(3)。 罐(1)和缓冲溶液(2)的壁对活化辐射是透明的。 悬浮在静止缓冲溶液中的小球(3)暴露于外部激活辐射(4),其从所有侧面均匀照射,直到发生完全光固化。 照射后,将固体小球在运行的蒸馏水和醇中洗涤,并在真空干燥柜中干燥,其中温度缓慢升高至不超过凝固组合物的玻璃化转变温度的水平。 将小球在该温度下保持一段时间,随后将其缓慢冷却至室温,目的是使剩余内应力最小化。 所提出的方法有助于生产非球面,包括渐变透镜,具有轴向和径向折射率梯度,以及中空球形和非球面微透镜。

    • 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.
