Manufacturing advances in large grazing-incidence optics

The fabrication of large grazing-incidence mirrors imposes needs for special fabrication and coating equipment, facilities, and raw materials. The economic realization of such optics has been readily accomplished through close interactions between the mirror users, the fabricator and the manufacturer of the raw material designated as mirror substrate. The manufacture and delivery of a 1.4 m flat and 1.0 m conical mirror are used to provide examples of recently demonstrated manufacturing technologies and effective interactions between participating organizations.
