Exploiting the Process Stability of Fluid Jet Polishing

Fluid Jet Polishing (FJP), a sub-aperture fabrication technique, is used for corrective polishing of geometries that are traditionally difficult to process due to tool restrictions. These geometries include concave spherical and aspherical surfaces. Furthermore the stability of the FJP process is demonstrated by correcting shape of a convex test glass using FJP calibrated on a concave spherical with a different radius. Finally FJP is shown to be able to remove mid-frequencies due to its small footprint size.
