Metrology – Measurement Challenge: How do you measure something that’s flexible, transparent, and/or has complex geometry?

Take a CPAP mask for example – it seems pretty basic in appearance… 

However, when it comes to assessing a CPAP mask from a measurement perspective – it proves to be very complex. In metrology, traditional measurement tools such as CMMs and Laser Scanners, are simply ineffective. Neither can successfully measure flexible, transparent, and/or complex objects. 

Since CMM relies on a touch probe contacting the surface, consequently it will deform the object producing erroneous results. Further more, CMM also has issues dealing with inaccessible features due to the geometry of the object.  

Laser and light scanners cannot measure transparent objects without the addition of a surface coating. Therefore, these measurement tools also struggle with items featuring complex geometry when line of sight to the object feature is not available.  

The solution to accurately measure a CPAP mask – or any other object that’s flexible, transparent, and/or has complex geometry – is X-ray Computed Tomography (CT). This measurement choice is ideal for a number of reasons. CT does not apply any force to the object. It is unaffected by transparent or shinny surfaces; and collects internal and external data all within the same scan. In addition, internal as well as external geometry features, such as wall thickness, can be measured even if there’s no physical access to the internal structure of the object. Viola!  

We have a variety of X-ray systems on-site to quickly, easily, and cost effectively produce successful NDT and metrology results for customers nationwide. We’ve seen a multitude of different objects from numerous industry sectors come in to our Inspection Services Department for x-ray inspection and metrology. Some are simple jobs and some are complex. We love a challenge, so be sure to contact us when you need help.

Take a Look: Our New M2 225/450

Avonix Imaging is proud to announce our new M2 225/450 large envelope inspection system is now available for contract X-ray and CT inspection services!

Located in our Maple Grove, Minnesota office our M2 225/450 is the only system of its kind in the United States that’s available for contract inspection services. We designed it to easily accommodate the wide range of products our clients request we scan. It’s a valuable addition to the array of equipment we utilize in our inspection services division.

In an effort to better meet the needs of our clients Worldwide, we built the M2 225/450 with a granite-based, high-precision, multi-axis manipulator. It’s paired with a Nikon 225kV microfocus X-ray source and a proprietary 450kV microfocus rotating target X-ray source. It features both an area detector as well as Nikon’s proprietary CLDA (curved linear diode array). In addition, it has our two-position detector panel shift option to provide nearly twice the scanning diameter envelope of conventional systems. Our newest M2 is housed in a panelized radiation-shielded enclosure and is equipped for helical scanning so even tall parts can be scanned in just a single pass.

This unique combination of superior manipulator design with both low-power and high-power microfocus X-ray sources from Nikon, means this system is able to scan a full range of products – from small electronics and hardware – to larger and higher density components such as turbine blades, castings, and complex additive manufactured parts.

We are dedicated to continually providing the best equipment possible for our client’s X-ray and CT nondestructive testing needs. For more information about our new M2 225/450, or any Avonix Imaging products or services, please give us a call at 855-228-6649.

Nikon Metrology Case Story: Saline Lectronics

Nikon Metrology Case Story: Saline Lectronics - Avonix Imaging Blog

Nikon Metrology Case Story: Saline Lectronics

Nikon Metrology has revolutionized defect analysis for electronic components for one Michigan company. Saline Lectronics is an electronics contract manufacturer, founded in 2002 and located in Saline, Michigan. Their experienced team of electrical, mechanical, test, and quality engineers solves the most complex and technical challenges for their customers. Therefore, it’s important for them to utilize the best equipment available. Saline Lectronics invested in the Nikon XT V 160. This offers the most accurate and reliable defect analysis of their customers’ highly complex, extremely dense circuit board assemblies.

Traditionally, the electronics manufacturing industry has relied on 2D X-rays systems or manual visual inspection to determine whether a connection is acceptable. However, these methods are subjective and can be unreliable. Nikon specifically designed the XT V 160 for use in production and failure analysis laboratories. This offers Saline Lectronics technicians a reliable, highly magnified look at component connections that ultimately saves time during both the build and troubleshooting processes. In addition, the non-destructive process offers a real-time, automated system for clear, pass/fail reporting.

Avonix Imaging partners with Nikon Metrology to provide world-class industrial x-ray and CT imaging equipment to companies like Saline Lectronics in the U.S. and internationally.

Year In Review 2016

Year In Review

As we begin 2017, Avonix Imaging has much to celebrate from the past year. We’d like to share some highlights as we look at our year in review.


As Avonix Imaging continues to grow its reputation and name in the industrial x-ray and computed tomography (CT) industry, we’ve also grown our staff to accommodate our clients’ needs. In 2016, our staff doubled, adding top-quality personnel to strengthen the areas of electrical engineering, equipment services, and contract inspection services. Our team is dedicated to exceeding expectations both in the quality of the imaging and the customer service provided, and continues to operate with the high standards and values of company founders Jeff Diehm and Brian Ruether.


In 2016, we embarked on a project to develop and build our own walk-in x-ray enclosure with an Avonix large-format manipulator system that will allow us to inspect larger parts and higher density materials with a dual 225/450 kV Nikon micro-focus system configuration. This will be an immense benefit for our customers, whether they are looking to purchase a system of this caliber or utilize our contract inspection services.

New Location

The year’s most visible change for Avonix Imaging was the move to our new location. We purchased a building and relocated from our original office in Plymouth, Minnesota, to a larger facility in Maple Grove, Minnesota, with an expanded applications and demo lab as well as a high-quality assembly area for our systems integration efforts. As a result, this allows us additional capabilities in all aspects of our business.
