Zygo Corporation Key Developments

Zygo Introduces Miniature Optical Position Sensor

Zygo Corporation announced the introduction of the new ZPS(TM) absolute position measurement system with ultra-compact optical sensor technology. The ZPS system enables high-precision measurement and positional control for advanced applications, such as deformable optics, lens positioning systems, and fine stage control. The ZPS system provides high-precision, non-contact absolute position measurements on up to 64 synchronized channels. Key features include a new ultra-compact optical sensor and hardware platform that delivers superior sensitivity, resolution and stability over a range of 1.2 mm. The advanced optical sensor generates virtually no heat and is insensitive to electromagnetic interference, achieving measurement resolution of 0.01 nm with better than 1 nm/day measurement stability. In addition, the ZPS system utilizes fiber optic cabling that allows for the use of a remote sensor location without impacting the measurement data. Optional accessories enable real-time automatic compensation for changes in ambient environmental conditions.

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.
