XUV multilayered optics for astrophysics

Abstract
High quality multilayered optics operating in the extreme ultraviolet are now being fabricated by a number of laboratories and their use in astronomical observations from space has already begun. Many other applications are planned and future instruments involving multilayers hold great promise for the field of astrophysics. This paper presents an overview of the current status of multilayer-based astronomical instrumentation, observations that have already occured and some plans for the future
