ABSTRACT:
For reducing absorption in a refractive element, the present invention relates to a refractive element (10, 20), suitable for refracting x-rays, comprising a body with low-Z material having a first end adapted to receive rays emitted from a ray source and a second end from which the rays received at the first end emerge. The refractive element comprises columns of stacked substantially identical prisms (21). The invention also relates to lens element.
