Optics For X-Ray Astronomy

This paper describes a large grazing incidence x-ray telescope that is being prepared for use in a spectrometer for x-ray astronomical observations. The telescope is figured by diamond turning and polished by applying an acrylic lacquer that is overcoated by a thin film of tungsten to provide high x-ray reflectivity. The current status of our research in multilayer deposition is presented and some astronomical applications of multilayer mirrors are described.
