| Popis: | Refractive X-ray optics, the physical fundamentals of which were considered by us previously [1], is presented mainly by focusing devices. Among them, an important role is played by compound lenses, the constructions of which are based on the additivity of optical forces of individual lenses. The law of additivity is experimentally proved for the X-ray range [2] by the example of a set of identical lenses having a constant curvature radius. It should be noted that the possibility of a stage-by-stage increase in the optical forces of individual lenses due to reducing the radius of circular apertures was indicated already in the first description of compound lenses [3]. Previously [4], we designed and investigated the planar lenses from silicon, where the curvature-radius scale reduction was introduced for individual lenses. The described type of planar lenses is considered nowadays [5] as most prominent for focusing the beams in the nanodimensional range. In this work, we describe the compound lenses, which were created for the first time with the curvatures-radius scale reduction and the rotation profile by the method of laser stereolithography from photopolymeric materials. |
