Reflective X-ray Optics LLC (RXO) provide high-performance multilayer X-ray optics solutions for science and industry. The firm produces custom multilayer coatings for NASA's solar physics instruments and X-ray coatings for the NuStar mission. The firm is also engaged in on-going, federally-funded research projects that are aimed at the development of new multilayer coatings and related technologies having improved performance in the EUV, soft X-ray and hard X-ray bands. Multilayer Coatings make use of the principle of optical interference to achieve high reflectance at normal incidence in the EUV and soft X-ray bands, and in the hard X-ray band at grazing incidence angles that are several times larger than those possible using front-surface mirrors. Their high reflection efficiency has enabled remarkable advancements in a variety of scientific and technological disciplines over the past three decades, particularly solar physics and astronomy, but also microlithography, ultrafast science, plasma diagnostics, synchrotron optics, and many other areas as well.
