There are several misconceptions about appliance optical technologies to admeasurement altered surfaces in altered kinds of environments. AZoM talks with Michael Schmidt about how ZYGO is developing technologies that affected the misconceptions.
Zygo Corporation was accustomed about 50 years ago, initially conceived as a arch architect of aerial attention plane-parallel optics. These types of eyes were acclimated both for accessory applications as able-bodied as in bartering applications. To aftermath these absolute high-end optical components, our engineers bare a way to authorize the components. From centralized development, the aboriginal commercially available, high-precision, non-contact Fizeau interferometer was created. From this creation, both a bazaar was accomplished as able-bodied as the ZYGO Instruments Division, for which I work.
The accessories that I currently focus on are the microscope-based systems – what we alarm the non-contact optical profilers. The bazaar that I currently abode is the attention machining and automotive market.
A few things which abstracted ZYGO from our antagonism is our adeptness to assignment anxiously with our barter and ascertain their needs. Focusing on our barter helps artifice the development aisle we booty with apparatus innovation. From ysis and engineering to business and sales, the barter and their needs are consistently the focus. Continuous accession generates above technology and performance, acclamation our barter aplomb in metrology and, in turn, their products.
One of the best cogent absolute impressions of the ZYGO cast which our barter admit is the akin of pre/post-sales support. With our world-class Advanced Applications Group and Field Service Team, our barter are assured affection and expedited assistance.
My absorption in attention machining stems from my father. A German immigrant accomplished in apparatus apparatus making, he eventually founded his apparatus and die aggregation in the United States. I would watch him boggle and apparatus his creations in the garage, consistently afraid by what could be created.
After starting with ZYGO, I confused to our German appointment to abetment with applications development for some of the best accustomed brands in German manufacturing. Abundant of this development occurred because agent injector sealing surfaces could no best be abstinent with stylus-based equipment. With acutely bound blueprint on apparent acerbity and form, any acquaintance apparatus could mar the surface, thereby creating a aperture aisle aback the injector is beneath pressure. Therefore, non-contact metrology was required, and ZYGO optical profilers were readily adopted for their aerial repeatability and robustness for the branch floor.
One trend which we are afterward anxiously is accretion manufacturing. The adeptness for manufacturers to book apparatus has awfully aerial abeyant to change the accomplishment mural in the future. Currently, there is abundant ysis to access the book resolution and abate the bulk of post-processing appropriate for a final product. Alive with several universities, ZYGO accessories is acceptable advisers to acknowledgment questions on apparent texture, structure, and quantifying accretion accomplishment processes.
One of my key responsibilities is actuality complex with our automotive OEM manufacturers and their suppliers. With accepted regulations on emissions abridgement as able-bodied as bigger agent efficiency, demands on the capabilities of accomplishment accessories accept expanded. With agent weight reduction, the ‘turbo-fication’ of engines, and added artistic solutions, automotive manufacturers are attractive to new machining technologies to aftermath tighter tolerances, stronger components, and smoother surfaces. This aggregate of needs fits the non-contact optical metrology apartment of capabilities altogether for actual acknowledgment to the action engineer.
If we accede the apparatus independent in automotive transmissions, the apparent arrangement should be such that it is not badly noisy, but is acutely efficient, and should authority up to the circadian stresses for the lifetime of the vehicle, if possible.
By appliance our ZeGage™, benchtop non-contact optical profiler, manufacturers can barometer their acid or acid action about instantly by barometer the accessory abut apparent for ambit which chronicle anon to the triogy of the system.

Moving on from gears, the light-weighting of engines is accession access for accretion efficiency. This introduces the spraying of bores with acutely able-bodied thermal coatings on aluminum blocks, rather than appliance abundant adamant engines. These spray-on surfaces can be actual asperous and charge to be inspected for pores and defects which can affect the acid that takes abode after in the process. With our instruments’ advanced activating range, we can calmly admeasurement surfaces which are actual rough,highly sloped, or mirror-like polished. The instruments are abundant for barometer not alone apparent texture, but additionally for added appropriate ysis items, such as porosity, allotment form, and some GD&T.
There are a few altered types of misconceptions. The aboriginal one is apparently that the arrangement doesn’t assignment able-bodied on the assembly floor. The absoluteness is that we accept abounding systems that are acclimated on the assembly attic every day. Moreover, we’ve developed technology to abate some of the added accepted sources of beating begin in these environments. One such accession is our SureScan™ technology, which allows our barter to accept aplomb their abstracts will be repeatable, no bulk area in the branch our apparatus resides.
We accept abounding instances area our systems are out on the assembly attic appropriate aing to acid or acid machines. This helps abate the bulk of time bare for a action architect to set up the tool, rather than bringing a set of genitalia to a metrology room, barometer the parts, bringing it back, resetting the machine. The abridgement in ysis time helps abatement the cardinal of defects that appear off that system.
The additional delusion is account or affluence of use. One of the best accepted $.25 of acknowledgment that we get from our barter is that the apparatus and the software are so abundant easier to use than added technologies. With ZYGO Mx™ software, the user can bound focus on the allotment apparent and attain a altitude with a distinct on columnist – behindhand of whether the allotment is bland and compatible or acutely rough.
Our technology is based on Coherent Scanning Interferometry (CSI), and while several competitors additionally action instruments with CSI capabilities, ZYGO’s Coherent Scanning Interferometry is unique. Independent aural abounding ZYGO patents is a adherence to the advance of CSI technology. Our SureScan™ technology mitigates the furnishings of automated vibration, which could aftermath poor altitude repeatability. There is additionally an advantage for oversampling, acceptance our CSI-based instruments to admeasurement surfaces that accept low reflectivity, are awful sloped, or are acutely rough.
In addition, ZYGO offers the widest alternative of interferometric objectives on the market, with magnifications alignment from 1X to 100X. Abounding of our objectives are absolutely different to ZYGO, including several specialty objectives, such as those with actual continued alive distances, to accredit key applications. ZYGO can do this due in allotment to our ancestry as an eyes company, with abysmal optical expertise, and the adeptness to accomplish these absolute optical assemblies. .
Compared with added types of technologies, such as confocal or focus variation, which admeasurement actual awful angled surfaces or acutely asperous surfaces, there has been a accepted delusion that CSI does not accept the aforementioned capabilities. As acicular out, this is false. This is one of the affidavit barter accept the innovative, high-quality, technology that ZYGO provides.
The ZeGage™ Pro non-contact optical profiler
We are always evolving apropos software and hardware, based on our interactions with customers. A lot of this comes aback to aloof basal business attempt such as alert anxiously to the barter and acclamation their needs.
We are always adorning the user’s acquaintance with the software and hardware. One archetype is the contempo addition of the “Smart Setup” feature. This software affection helps the user to find, focus, and access abstracts with aloof a on press. It sounds elementary, but with the ambit of surfaces to be measured, and the combinations of objectives ZYGO offers, we let the software do the assignment for the customer, so they can absorb added time allegory the after-effects and beneath time ambience up to measure.
With all the options barter accept for price, performance, and reliability, we at ZYGO strive to accomplish them feel adequate and assured that ZYGO was the appropriate choice.
