Abstract The ROSAT mission, which is currently being prepared in W.-Germany, will perform the first soft X-ray all-sky survey by means of a large imaging X-ray telescope. Detailed calculations under the cost, volume and mass constraint of the satellite being a Shuttle payload have led to a design of the imaging optics with optimized geometry. The mirror system is of the Wolter type I configuration and includes four nested shells with a maximum aperture of 835 mm and a focal length of 2400 mm. The on-axis angular resolution of the mirror assembly has been specified to 5 arcsec with a scattering level as low as 3% for single reflection at 1.5 keV photon energy. Construction and technology studies have been completed by now and manufacturing of the first mirror shell has begun.
