We describe a technique of shape modification that can be applied to thin walled (similar to 100-400 mu m thickness) electroformed replicated optics or glass optics to improve the near net shape of the mirror as well as the mid-frequency (similar to 2-10 mm length scales) ripple. The process involves sputter deposition of a magnetic smart material (MSM) film onto a magnetically hard material (i.e., one that retains a magnetic field, e.g., the material in hard disk drives). Since the previous report, we have made extensive measurements of the deflection versus magnetic field strength and direction. Here we report those results along with detailed finite element analysis modeling.
