Abstract
The development of techniques for the fabrication of multilayer coated mirrors which can function as energy selective X-ray and XUV mirrors at normal incidence has greatly expanded the options available to the astronomical spectroscopist. We have developed a rocket spectroheliograph which utilizes multilayer optics in three configurations : i) As Cassegrain telescopes for imaging at 256 Å (He II) and 173 Å (Fe IX, X ) ; ii) As tertiary mirrors used with a conventional Wolter I telescope for imaging at 44 Å (Si XI, XII), 173 Å, and 256 Å ; iii) As off-axis spherical mirrors for imaging at 44 Å and 256 Å. We report on laboratory images and performance measurements obtained with these optical systems, and briefly on Solar Observations.
