Zygo Corporation Key Developments

Zygo Introduces Nomad Portable Optical Profiler

Zygo Corporation has introduced the new Nomad portable optical profiler. The Nomad system employs advanced optical technology and advanced 3D non-contact metrology in a lightweight, compact and portable package, enabling metrology on samples that were previously impossible or impractical to measure. Nomad leverages ZYGO's Coherence Scanning Interferometry (CSI) and SureScan technologies for vibration robustness to provide the performance of a workstation in a compact design built with portability in mind. In applications as varied as precision optics polishing and the finishing of sealing surfaces on an automotive engine, surface roughness and waviness are key functional parameters. By using ZYGO's extensive range of parfocal objectives from 1.4x to 100x magnification, the Nomad profiler enables critical metrology in an easy to use and quantitative way. Nomad runs ZYGO's internally developed Mx software, for enhanced data visualization and quantification of step heights, texture, and volumetric features. Its highly-optimized metrology software also provides added capabilities for regions analysis and advanced applications. The instrument includes a novel desktop stand for the system with an integrated metric breadboard for customers to adapt small-scale fixturing. The instrument's breadboard and stand enable the Nomad to be utilized not only as an on-part metrology solution but also as a desktop profiler for smaller samples, providing additional instrument flexibility. Whether measuring directly on large parts or utilizing the stand for smaller samples, the instrument's configurable application recipes and custom scripting capability allow manufacturers to easily tailor the measurement process and combine multiple metrology steps on a single station.

Zygo Corporation Introduces COMPASS 3D Non-Contact Metrology Instrument

Zygo Corporation introduced the COMPASS 3D non-contact metrology instrument as a solution for measurement of small aspheres. Multi-element aspheric lens assemblies are now ubiquitous in consumer electronics devices such as mobile phones, tablets and personal computers. Fabricating and aligning those optical sub-assemblies presents significant challenges due to the difficulties in measuring smooth, highly-sloped, transparent surfaces and complex mechanical geometries. The COMPASS metrology system overcomes those obstacles by measuring shape, texture and the mechanical alignment features of both the lenses and the precision molds used to form them. The unique feature set of COMPASS enables a truly comprehensive small asphere measurement solution. The resulting high-resolution 3D map of the optical surface confirms adherence to the target design and provides full-surface texture analysis. Those capabilities can characterize asymmetries in surface form and localized surface defects that other metrology methods cannot quantify. In addition, COMPASS can evaluate lens centration, thickness, and other relational parameters necessary to predict final assembly performance.

Zygo Corporation Releases Verfire XL Interferometer for Large Aperture Form Metrology

Zygo Corporation announces the release of the Verifire XL high-precision Fizeau interferometer for the simple and accurate characterization of flat surfaces up to 12 inches (300 mm) in diameter. Designed for measuring large plano surfaces, such as mirrors, semiconductor wafers, or optical windows, the Verifire XL is a turn-key solution incorporating staging, accessories and production-oriented technology. The downward-looking orientation of the Verifire XL system with a heavy-duty part stage enables quick and easy metrology for a wide range of test parts. The instrument features an integrated reference optic with ZYGO's proprietary full area calibration enabling metrology to better than 30 nm PV over the full 300 mm aperture. The Verifire XL system comes with an integrated TMC vibration isolation platform and ZYGO patented QPSI vibration-robust acquisition technology. Those features permit precise, reliable metrology, even in production environments where vibration can degrade measurement data using other acquisition techniques. Measurement and analysis of surface topography on the Verifire XL interferometer is handled by ZYGO Mx metrology software, the industry s most powerful data analysis and visualization platform. In addition to QPSI acquisition, the Mx software also includes ZYGO new Smart Averaging feature, which automatically provides the best possible measurement in the shortest time. Verifire XL interferometer is an application-centric model of ZYGO's Verifire line of phase-shifting laser Fizeau interferometers. The system shares their robust and stable design, a long-life high-powered laser source and high-speed, high-resolution camera for unmatched data and instrument reliability in the most demanding applications. The Verifire XL interferometer is now available worldwide for purchase.
