ABSTRACT:
For obtaining a high reflectivity, even when the thickness of periodic structure is reduced, in a multi-layered mirror consisting of alternate layers of a first substance showing a larger difference vacuum in the refractive index in the soft X-ray region and a second substance showing a smaller difference, a nickel-chromium alloy containing chromium in at least 5 wt. % is used as the first substance of larger difference. In a preferred form of the mirror, the second substance of smaller difference in refractive index is vanadium oxide.
