Vibration-Tolerant Interferometry QPSI™ Technology Vibration-Tolerant Interferometry QPSI™ Technology

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.

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.

Verifire™ Laser Fizeau Interferometer Verifire™ Laser Fizeau Interferometer

Nexview™ 3D Optical Surface Profiler Nexview™ 3D Optical Surface Profiler

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.

  • When Custom Costs Less Than Standard: The Benefits And Flexibility Of Custom Optical Assemblies
    When Custom Costs Less Than Standard: The Benefits And Flexibility Of Custom Optical Assemblies

    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.

  • The Meaning And Measure Of Vertical Resolution In Surface Metrology
    The Meaning And Measure Of Vertical Resolution In Surface Metrology

    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 For Surface Structure Analysis
    Interference Microscopy For Surface Structure Analysis

    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

  • Coherent Artifact Reduction System (CARS)
    Coherent Artifact Reduction System (CARS)

    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.
