The device according to the first invention is adapted for producing the image of an object with the aid of radiation that either has been transmitted therethrough or excited therein or else scattered thereby. A lens is placed between a radiation source and a means for placing the object, or between the latter means and an image-forming means that registers the distribution of intensity of the radiation incident thereon (or else in both of these spaces), which lens is made according to the second invention and adapted for converting a flux of particles (that is, focusing a diverging or quasi -parallel radiation, forming a quasi-parallel radiation from a diverging one, monochromatization, spatial separation of different-energy particles contained in an original polychromatic flux, etc.). The lens comprising a set of radiation transfer channels (predominantly in the form of glass mono- or polycapillaries) is characterized in that the channels are arranged orderly across the lens cross-section with the obcervance of axial symmetry (i.e., mirror, central, or rotations1), whereby interference of the radiation emerging from the lens occurs. The channels may be grouped into modules 30 which are arranged orderly and symmetrically, each of the modules being in turn established by smaller modules 31 featuring the same number, shape, and mutual arrangement.
