Technologies · Dimensional metrology
Full-field measurement at the speed of production
Optical 3D metrology captures millions of points in seconds, delivering complete dimensional insight far faster than point-by-point probing.
Optical 3D Metrology
Optical 3D metrology uses structured light or fringe projection to capture the full surface of a part as a dense point cloud. The result is fast, high-resolution measurement of complex shapes — well suited to first-article inspection, deformation analysis and reverse engineering.

Quality and manufacturing engineers needing fast, full-field dimensional data.
From part to traceable result
A high-level view of the measurement workflow — the exact setup is matched to your application.
Optical data capture
The part is illuminated with structured light, fringe patterns or focus-variation optics while a high-resolution sensor records the full surface — no probe contact required.
Point-cloud reconstruction
Software converts the captured images into a dense 3D point cloud, representing millions of measured points across the visible geometry.
Alignment to CAD
The point cloud is aligned to the nominal CAD model so measured geometry can be compared directly to design intent.
Deviation & reporting
Colour-map deviation analysis, GD&T evaluation and dimensional reports are generated automatically, delivering traceable OK / NOT OK results.

Questions engineers ask
How accurate is optical 3D metrology compared with a tactile CMM?
Modern focus-variation and structured-light systems reach sub-micrometre vertical resolution and deliver traceable results comparable to tactile CMMs, while capturing the full surface rather than discrete points. The right choice depends on your tolerances, part size and feature type — something we assess during a consultation.
Can optical metrology measure reflective or shiny surfaces?
Yes. Focus-variation systems handle a wide range of surface finishes, including polished and reflective materials, and polarisation or ring-light options extend coverage further. We validate your specific parts before recommending a configuration.
Is optical 3D metrology suitable for the production floor?
Yes. Robust, automated and cobot-integrated optical systems are used directly in production for first-article and in-line inspection, with automated CAD-based reporting that non-metrology staff can run.
