This paper discusses the concept design of the mirror assembly for the Solar-A soft X-ray telescope to be launched aboard the Japanese Solar-A satellite in 1991. The design uses two hyperbolic surfaces (instead of the parabola-hyperbola design of a conventional Wolter type I design) and a special software for linking the structural/thermal finite element analysis programs to the optical-performance-prediction programs. In order to make it possible for the system to survive launch and to guarantee the maintenance of alignment between two hyperbolic optical surfaces, the telescope is designed with both surfaces in tandem on one substrate. The design features were successfully demonstrated on a flight model and were fully qualified on the mass model during vibration tests.
