Look at the Entrance Aperture of the ROSAT Telescope
Look at the entrance aperture of the ROSAT telescope. Four parabolic-hyperbolic mirror pairs fitted into each other form a Wolter Type-I Telescope with a focal length of 2.4 m, of which ring segments - divided by 16 radial struts - are seen. Each mirror is 50 cm in length and the diameter of the largest mirror is 84 cm. With it, ROSAT carries the largest X-ray telescope ever built. Its mirror surfaces have a residual roughness of less than 3 Å, which make them, after a final polishing, the smoothest mirrors ever produced for a grazing-angle telescope.
