Measure complex, curved surfaces others can’t reach!

Some of the most critical features are also the hardest to reach—especially curved interfaces and recessed geometries where traditional tools fall short.

That’s where the 4D InSpec stands out:
Designed for flexibility and precision, the 4D InSpec makes it easy to access and accurately measure radius of curvature in challenging locations—without compromising speed or accuracy.

✅ Why it matters:
• Reach into tight or curved interfaces with ease
• Capture precise, repeatable radius measurements
• Eliminate guesswork from difficult geometries
• Improve confidence in inspection and final quality

📢 Onto Innovation’s 4D Technology Introduces 4Di InSpec™ SR System for Shop-floor Surface Roughness

Onto Innovation’s Tucson-based subsidiary 4D Technology announced today the launch of the 4Di InSpec™ SR roughness measurement system – a novel, portable, vibration-immune optical system for high-precision 3D surface roughness measurement at the point of use.

The 4Di InSpec SR employs patented technology for rapid surface measurements unaffected by vibration. Rugged and easy to use, the system accurately measures roughness right on the shop floor, in a wide range of environmental conditions.

“This launch represents a new class of shop-floor optical surface roughness measurement technology,” said Craig Manning, VP of Onto Innovation. “By expanding our product portfolio with a portable, vibration-immune optical profiler, we’re giving customers a powerful new way to solve some of their most challenging surface roughness problems – delivering lab-quality, 3D roughness data directly on the shop floor for faster decision making.”

Stop scrapping good parts! See scratches in a whole new dimension.

Are you still relying on visual inspection or 2D measurement to evaluate surface scratches? You could be leaving yield—and profit—on the table.

Traditional methods are subjective and often overly conservative, leading to unnecessary scrap. In contrast, 3D optical gauging provides quantitative, repeatable measurements of scratches—so you can make confident, data-driven decisions.

What 3D measurement delivers:
• True depth, width and volume of scratches
• Objective pass/fail criteria (no guesswork)
• Improved consistency across operators and sites
• Reduced false rejects and higher yield

With precise 3D data, manufacturers can directly compare defects against specification callouts, ensuring only truly compromised parts are rejected—while good parts move forward.

The result?
✔ Less scrap
✔ Higher productivity
✔ Better quality confidence

Next up in Milan, Onto's 4D Technology, alongside distributor Quantum Design Italy, will be exhibiting at ASME Turbo Expo 2026.

At booth , our 4D InSpec surface gauge will be on display where visitors can view live demonstrations of our handheld, precision instrument for non-contact surface defect measurement. Unlike high-end metrology systems, it is rugged, flexible and affordable, and can measure a wide range of part geometries in the most challenging environments.

We hope to see you there!

Another common application for the 4D InSpec are fir tree edge break measurements, similar to chamfer holes. Rather than use precious time to make a casting of that fir tree surface, it’s so much faster to point and click with the handheld 4D InSpec.

With a 45-degree angle and perpendicular positioning of the instrument, we can quickly capture this data. The live video provides a green colored indication when a measurement is ready to be captured then analyzed, making the process seamless and user friendly.

To measure in chamfer holes, the 4D InSpec is our go-to system to achieve this data. Watch how easy it is to line up the emitted light and with a click of a button, capture the intended data. While in-use, the live video feed is visible to ensure the area of interest is captured in the field of view.

Then through the analysis software, the 3D measurement is ready for review.
