Industrial Measurement

Handheld, shop floor, and automated surface metrology

With ultra-fast imaging times, many 4D products prove capable of measuring when attached to a robot, or even when handheld. These features mean industry technicians can gain high-precision surface data inside a production tool—for in-process updates—or on a turbine engine that’s still attached to an airplane wing—saving untold hours of dismantling.

Now: 3D, high resolution handheld 

In the past, inspectors in many industries had to choose between inexpensive, but low-resolution surface gauges or high-resolution metrology instruments that required controlled measurement labs and cost many time more. 4D gauges offer the best of both worlds: high-resolution, 3D measurements with one-button operation that can be used anywhere in the factory or lab.

Measure in the shop, right now

The days of parking parts in a measurement lab queue are over. Now you can measure peen marks, edge break and more on the shop floor. Quantify defects on components and assemblies, anywhere in the shop. And determine the features of paint layers that truly lead to outstanding finishes.


Versatile, long standoff has reach

4D gauges make 2D profile measurement a thing of the past, providing many high-resolution, 3D surface maps in the time it takes to set up and acquire one low-resolution 2D profile trace.

Portable and compact, measuring in challenging locations, or at difficult angles is easy, without the time, mess and expense of using replication materials.

With its long stand-off, you can use a fold mirror to sample hard to reach spots in real time.

With 4D surface and finish gages, you can measure surface quality with high precision, even in an automated environment, or in the turbulence caused by a large separation between your part and the metrology system.

It means you can attach your metrology system to a robot and sample at high speed, or take a measurement of a surface that is changing under stress.

Industrial Challenges

Aerospace and Defense

Aerospace and defense contractors rely on 4D Technology’s dynamic laser interferometers and optical profilers for accurate measurements.

Aviation and Automotive

Part inspection for high value machinery like aircraft engines requires high-volume, in situ defect qualification using non-contact 3D imaging of features.


Medical applications and biological research present a challenging set of requirements for measurement systems, including constantly changing subjects, difficult environmental conditions, and stringent controls, particularly for in vivo measurement.

Optics Manufacturing

4D Technology dynamic laser interferometers enable precision measurement right on the factory floor, without vibration isolation.


Semiconductor manufacturers count on 4D measurement instruments to ensure quality throughout the manufacturing process.
