The HDX system includes all of the features of the Verifire HD, and adds enhancements such as the best-in-class imaging and resolution for high instrument transfer function (ITF), and superior characterization of mid-spatial frequency content and high-slope surface deviations.
The new ZPS™ System from Zygo Corporation is designed to measure absolute position via ultra-compact optical sensors with a resolution of 0.01 nm and less than 1 nm of non-linearity. The system is typically used for closed-loop feedback systems that require continuous streams of high-precision position data from multiple sensors to maintain precise positioning and alignment.
Precision interferometric metrology faces the challenge of environmental vibrations which can ruin countless precision measurements. Vibration affects measurement results and spatial frequency analysis, making it difficult to make high quality optics without reliable measurements. Zygo’s QPSI technology eliminates this problem with measurements that require no special setup or calibration, and cycle times are typically within a second or two of standard PSI measurements.
ZYGO offers the new APM650™ packaging metrology system designed to provide 2D and 3D measurements of a variety of surface features with sub-nanometer vertical precision and sub-micron lateral precision. This inspection tool is ideal for the automated measurement of panel based PCBs and other advanced packaging applications.
The Nomad profiler from Zygo Corporation is a small, lightweight portable optical profiler ideal for situations where the measurement of an object’s surface is too large for the measurement stage of a conventional workstation profiler.

The ZeGage™ is a scanning white light interferometer that provides 3D optical surface profiling for the measurement of precision surfaces that require non-contact metrology. Unlike other optical surface profilers, this system maintains high resolution at all seven of its magnification options. It’s also not affected by the environment it operates in. You can take it out of the QA lab, place it directly beside your production equipment, and still get a 3D surface roughness measurement of precision machined surfaces with nanometer level precision.
The Verifire™ interferometer is a true common-path Fizeau configuration that ensures accurate metrology and “ripple-free” phase measurements in vibration-prone environments. It is well suited for providing accurate surface metrology in both production and quality control environments.
The DynaFiz™ interferometer is a high performance laser interferometer designed to measure the surface form of optics in the presence of turbulent air, or in environments susceptible to extreme vibrations. The system’s long life, high powered HeNe laser source enables reliable metrology at the camera’s maximum shutter speeds of cavities with low reflectivity. This proprietary laser and optimized optical system in the DynaFiz system allows the interferometer to “freeze” the vibration during acquisition so that dynamic metrology can be conducted in environments that are too violent for traditional temporal phase shifting.
The Nexview™ 3D optical profiler microscope stands out amongst competitive products by its ability to measure the topography of virtually any surface, irrespective of roughness, large steps and segments, thin films, steep slopes, with feature heights ranging from < 1 nm up to 20000 µm. It does all this in 3D, without contact, and provides the best qualities of other profiling technologies (stylus, confocal, focus scanning) without their limitations.

Optical subsystems exist in a wide variety of configurations for a whole range of applications. Most of the parts that go into such optomechanical assemblies — laser and LED light sources, lenses, dichroics, filaments, detectors, spatial light modulators, and all the associated mechanical fixtures — are available as commercial off-the-shelf (COTS) parts. So it can be tempting to say that if you’re designing a new optical subsystem, you should just purchase the parts and build it yourself. But is that really the right choice? Here are a few questions you might be asking when you’re considering whether to build your own assembly or have it custom-made by an experienced design and manufacturing team.

Zygo’s QPSI technology eliminates the problem of environment vibrations with measurements that require no special setup or calibration. A ZYGO interferometer utilizing QPSI technology is capable of producing reliable high-precision measurements in the presence of environmental vibration from common sources such as motors, pumps, blowers, and personnel.
Understanding performance specifications is the first step in the process of selecting an instrument or technology for areal surface topography measurements. One of the more frequently cited parameters is known as “vertical resolution,” which is defined as the smallest surface height variation that can be detected. As a result of a review of instrument brochures, technical articles, and international standards, it was found that there is not a consensus regarding the meaning of "vertical resolution" and its numerical specification, which leads to a lot of confusion in the industry. It is important to re-evaluate the use of the term “vertical resolution” and identify a better way to characterize other instrument performance specifications.
Interference microscopy encompasses a wide range of techniques when it comes to measuring the many aspects of surface structures. Utilizing interference microscopy for these types of measurements includes the advantages of rapid, non-contact operation and rapid data acquisition, often at data acquisition rates in the millions of 3D image points per second. Due to its uniqueness among optical areal measurement instruments, interferometry has the benefit of high sensitivity to surface structures. This article discusses the principles of interferometric dimensional metrology applied to surface features best viewed in a microscope
Obstructing artifacts in interferometric data can come in many different forms, such as a “bulls-eye,” which can be caused by dust on an optical surfaced in the coherent beam path of an interferometer. These artifacts can print through on the height map and affect the magnitude and repeatability of the surface results. As a solution, ZYGO offers the Ring of FireTM extended source method for reducing noise and other artifacts. Building on this expertise, ZYGO has also developed a coherent artifact reduction system (CARS) that reduces noise from wavefront shearing, speckle, or mottle by a factor of up to 10 and allows for surface features to be resolved.
Optical profilers using Coherence Scanning Interferometry (CSI) have traditionally found it a challenge to measure highly sloped surfaces. Surfaces like these can be found in all industries and include optical micro-lenses, brightness enhancing structures, and machined cones. ZYGO offers CSI based profilers running Mx™ software with advancements in signal detection and processing that vastly improve the ability to obtain valid topography data from surfaces with high slopes.
Intelligence, surveillance, and reconnaissance (ISR) windows must demonstrate superior performance r to avoid compromising a mission’s success. Sapphire is extremely durable, scratch-resistant, withstands extreme temperatures, and transmits over a broad wavelength range of light.

When the Department of Defense decided its landscape flight simulators to train pilots required too large a display, too large an enclosure space, and felt a bit antiquated in general, the DoD looked for a helmet –mounted simulation solution to replace the traditional rear-projection screens they were using.
When an ophthalmologist removes the natural lens in a human eye that’s affected by a cataract, an artificial intraocular lens (IOL) is put in its place.
