WebOptical polishing is used when the requirement is for an ultrasmooth finish with only minimal defects for very specific quality and functionality on optical components. It removes a small amount of material from the surface of the source component, leaving a bright, reflective superfinish or microfinish surface. WebSpherical, aspherical, cylindrical, and freeform polishing of optics up to nearly 2 m diameters. Coherent uses a deterministic computer-controlled polishing technology that is volume scalable to fabricate high-performance optical surfaces in a variety of materials including standard and low expansion glasses, aluminum, beryllium, nickel, and ...

WebOct 1, 2011 · Oct. 1, 2011 The VIBE process is a full-aperture, conformal polishing process that uses high-frequency, random motion to rapidly remove sub-surface damage and eliminate mid-spatial-frequency surface errors. The process can also be used as a finishing step after deterministic sub-aperture polishing. FIGURE 1.
