ZYGO Launches Verifire Asphere+: Fast, Flexible, and Precise Asphere Metrology Middlefield, CT -Optical metrology leader Zygo Corporation — a business unit of Ametek Inc. — announces today that it will be revealing its Verifire Asphere+ — which represents the latest addition to the company’s VerifireTM series of laser Fizeau interferometers — at the SPIE.OPTIFAB event 18-21 October 2021 in Rochester, NY, USA. The Verifire Asphere+ ( VFA+) builds upon the success of the Verifire Asphere Interferometer, which was made specifically for fast, noncontact, high-resolution 3D metrology of aspheric surfaces. The VFA+ leverages the benefits of Fizeau interferometry through a unique combination of precise, high-resolution, fast, and full aperture metrology for axisymmetric aspheres. This allows faster convergence on deterministic polishing feedback for more efficient surface generation.
