MIDDLEFIED, CT – Zygo Corporation, a unit of AMETEK Ultra Precision Technologies, has added to its best-selling Verifire™ line of laser interferometers with the Verifire™ HD high-resolution Fizeau interferometer for surface form and wavefront metrology of optical components and systems. The new phase-shifting metrology instrument performs advanced characterization of precision optical surfaces.
A high-resolution camera and optimized optical design characterize the mid-spatial frequency content in optical surfaces – a critical need for high-precision applications. For versatility and precision, the Verifire HD interferometer is equipped with ZYGO’s patented QPSI™ vibration-robust acquisition technology that enables the system to maintain a high level of measurement accuracy in vibration prone environments.
Vibration that occurs with the use of traditional phase measuring acquisition can cause “fringe print-through,” a form of data noise that degrades results. With QPSI technology, however, phase-shifting measurements are virtually ripple-free. The Verifire HD system also can be configured to include CARS™ (coherent artifact reduction) technology to reduce spatial noise like speckle and bullseyes.
For the Verifire HD system, measurement and analysis of surface form, radius of curvature and transmitted wave front quality are supported with ZYGO’s Mx™ metrology software, the industry’s most powerful data analysis and visualization platform. Mx software includes a new Smart Averaging feature, which helps users obtain the best possible measurement in the shortest time period.
The Verifire HD interferometer uses ZYGO’s high-power, long-lifetime and frequency-stabilized laser source, which features high light efficiency for difficult metrology applications at a lower cost of ownership. The Verifire HD system, which accepts the industry-standard line of ZYGO interferometer accessories, is available now for purchase worldwide.
Zygo Corporation, a unit of AMETEK Ultra Precision Technologies Division, is a leading provider of optical metrology solutions, high-precision optics, and optical assemblies used in a wide range of scientific, industrial, and medical applications.
AMETEK, Inc. is a leading global manufacturer of electronic instruments and electromechanical devices with 2014 annual sales of $4.0 billion. For more information, contact Zygo, 21 Laurel Brook Rd., Middlefield, CT 06455-1291 USA. Telephone: +1-860-347-8506. E-mail: inquire@zygo.com
