Предложены сравнительно дешевые способы изготовления полуфабриката линзы, линзы (варианты) и полностью обработанной линзы (варианты), включающие обеспечение заготовки линзы 11, имеющей формующую поверхность заданной кривизны с оптическими свойствами и тыльную поверхность, предназначенную для шлифования и полирования на последующем этапе изготовления линзы. Заготовку линзы располагают относительно формы 13 с образованием узкой полости 14, 16 для формования внешней поверхности линзы с оптическими свойствами. В указанную полость подают смолу из материала с оптическими свойствами, содержащую инициатор, активируемый УФ-излучением. При этом смола по существу не содержит тепловых инициаторов. Затем осуществляют отверждение смолы с помощью подачи ультрафиолетового излучения и тепла. Тепло подают регулируемым образом для обеспечения выравнивания степени отверждения участков смолы, имеющих неодинаковую толщину. 6 с. и 18 з. п. ф-лы, 12 ил.

... 207,790. Deutsch, L., Thorn, I., and Amalith Chemische Industrie Ges. Nov. 30, 1922, [Convention date]. Processes; moulding gums and resins.-Condensation products from aldehydes and phenols are hardened by heat treatment in a bottomless mould sealed by a liquid, e.g. a solution of calcium chloride, magnesium chloride, or Glauber salt, or molten mass of specific gravity higher than that of the mass to be hardened. A container is partly filled with the solution &c., the moulds are inserted, and the mass filled in, after which a further quantity of solution is added to the container outside the moulds until its level coincides with that of the mass. The mass may be covered by an inert liquid, e.g. oil. The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of fusible alloys such as Wood's metal or Rose's metal as a sealing-material and solid paraffin or naphthalene as a covering-material. This subject-matter does not appear in the Specification as accepted.

A transparent capsule is manufactured by using a lower die case having a substantially semi-spherical inner surface and an upper die cast having a substantially semi-spherical outer surface. The radius of the upper die cast is slightly smaller than that of the lower die cast. Transparent resin in the space between the lower die cast and said upper die cast is uniformly and gradually heated and then cooled in order to harden the transparent resin. Thereafter, the upper die cast is separated from the lower die cast and the transparent resin formed in the shape of a sphere is removed from the die casts.

Three-dimensional (3D) hierarchical morphologies widely exist in natural and biomimetic materials, which impart preferential functions including liquid and mass transport, energy conversion, and signal transmission for various applications. While notable progress has been made in the design and manufacturing of various hierarchical materials, the state-of-the-art approaches suffer from limited materials selection, high costs, as well as low processing throughput. Herein, by harnessing the configurable elastic crack engineering-controlled formation and configuration of cracks in elastic materials, an effect normally avoided in various industrial processes, the present invention provides a facile and powerful technique to enable the faithful transfer of arbitrary hierarchical structures with broad material compatibility and structural and functional integrity. The present invention provides a cost-effective, large-scale production method of a variety of flexible, inexpensive, and transparent 3D hierarchical and biomimetic materials. 1.
