Abstract

We discuss a technique of shape modification that can be applied to thin walled (~; 100-400 micron thickness) electroformed replicated optics or slumped glass optics to improve the near net shape of the mirror as well as the mid-frequency ripple. The process involves sputter deposition of a magnetic smart material (MSM) film onto a permanently magnetic material. The MSM material exhibits strains about 400 times stronger than ordinary ferromagnetic materials. The deformation process involves a magnetic write head which traverses the surface, and under the guidance of active metrology feedback,locally magnetizes the surface to impart strain where needed. Designs and basic concepts as applied to space borne X-ray optics will be described.
