摘要
Traditional X-ray mirrors made from Zerodur and silicon carbide ave quite expensive because of the fabrication cost involved in achieving a very high surface finish of the order of 15 Angstrom or better. The cost of X-ray mirrors can be greatly reduced by using replication methods for producing the grazing-incidence type mirrors. This paper presents the optical and optomechanical design for a Wolter type I mirror and its mount, and the fabrication method used to produce a low-cost replicated nickel mirror. The finite element analysis results for this mirror ave also presented. The design and fabrication steps for the aluminium master mandrel used for replication are also discussed. A surface finish of better than 15 Angstrom was achieved for a such an electroformed mirror with a wall thickness of only 1 mm. Copyright (C) 1996 Elsevier Science Ltd.
