Introduction

  • Many space and large mirror optical applications require a light-weighted support design. 
  • Light-weighted optics that have been polished using conventional techniques, often show print-through, or quilting errors.
    • Conventional polishing techniques apply normal forces that can deform non-supported surface areas causing variation in polishing rate. 
  • Material removal from MRF is a result of shearing forces and very little normal force is applied to the surface of an optic; therefore, MRF does not cause any print-through or quilting. 
  • Due to its deterministic nature, MRF can also correct pre-existing print-through errors.
