Optical Measurement of Complex Geometries
Capture full 3D geometry on parts that defeat tactile probes and comparators.
The inspection problem
Complex or micro-features — cutting-edge preparations, turbine blade tips, micro-fluidic channels, small screws — cannot be measured reliably with tactile probes without damaging the part or losing detail.
Why it matters
Dimensional drift on complex geometries hides in aggregate metrics and shows up as field failures, tool wear, and out-of-spec assemblies.
Which method fits your part?
Every method has a sweet spot and a limitation. Choose based on defect, geometry, throughput and access — not on habit.
Optical 3D metrology (Focus-Variation)
When it fits: Steep flanks, high dynamic range, small features on metals and other materials.
Limitations: Very dark, transparent or highly absorbent surfaces need special preparation.
Industrial CT
When it fits: Internal geometry and features not accessible from outside.
Limitations: System cost, cycle time, and material density considerations.
