Abstract
This paper describes optical metrology and an alignment/integration sequence which has the potential to secure sub arc second accuracy for a single focus Wolter type I telescope like XEUS. The same basic principle could be used for any grazing incidence Wolter type I design in which the aperture is divided into sectors and the Wolter surfaces are manufactured as sector plates rather than continuous surfaces of revolution. If such a scheme could be implemented then the performance of XEUS would be limited by the quality of the mirror plates and the plate mounting rather than the integration and alignment procedure.
