The invention makes possible to increase the degree of radiation focusing by the lens, to use particles of higher energies, and to increase the coefficients, depending on these factors, of the devices, the lens is used in. Thus the sublens (18) of the least degree of integration represents a package of the channels (5), which is growing out of joint drawing and forming the capillaries, which are laid in a bundle. The sublenses of each higher degree of integration represents a package of sublenses of the previous degree of integration, which is growing out of their joint drawing and forming. The sublenses are growing out of performing the said operations at the pressure of the gaseous medium inside the channels being higher than the pressure in the space between the sublenses of the previous degree of integration and at the temperature of their material softening and splicing the walls. To produce the lenses a bundle of stocks (capillaries) in a tubular envelope is fed to the furnace (at the first stage) or stocks, produced on the previous degree, and the bundle is drawing from the furnace at the speed, exceeding the speed of feeding. The product is cut off on stocks for the next stage, and at the final stage the product is formed by varying the drawing speed, after what the parts with formed barrel-shaped thickenings are cut of.

Les inventions permettent d'augmenter le degré de focalisation de rayonnements au moyen d'une lentille, d'utiliser des particules à énergies plus élevées et d'améliorer ceux des paramètres des dispositifs utilisant une lentille qui dépendent de ces facteurs. La lentille se présente comme un ensemble de sous-lentilles (18, 19) à degrés d'intégration différents, la lentille ayant le degré d'intégration le moins élevé se présentant comme un ensemble de canaux (5) obtenu par l'étirage et le formage conjoints de capillaires regroupés en un faisceau. Chacune des sous-lentilles (19) à degré d'intégration plus élevé se présente comme un ensemble de sous-lentilles à degrés d'intégration précédents, obtenu par l'étirage et le formage conjoints desdites sous-lentilles. Les sous-lentilles sont obtenues au moyen des opérations décrites dans l'invention, avec une pression du milieu gazeux à l'intérieur des canaux qui est supérieure à celle dans l'interstice entre les sous-lentilles du degré d'intégration précédent et avec une température suffisante pour ramollir le matériau constitutif et fusionner les parois desdites sous-lentilles.
