Paper Abstract

The soft x-ray region covers wavelengths longer than those of medical x rays, where vacuum is required for propagation (A ^ 5 A). Absorption of all materials increases with increasing wavelength in this region, and the absorption length of, the most transparent specimens is around 1 pm for A « 50 A. Conventional lens and mirror systems cannot be built for soft x rays (due to absorption in lenses and low reflectivity of normal incidence mirrors), and only three types of imaging systems remain possible for soft x rays: grazing incidence reflectors, multilayer mirrors, and diffractive elements such as zone plates. Soft x-ray optics has advanced dramatically during the last decade.
