Medical Device Part Inspection

Q: How small can the defects be?

With the OV80i and appropriate magnification, we have successfully detected scratches under 0.1mm in production environments.

Detect scratches, dents, flash, and assembly defects on small medical parts

What It Is

Surface and geometry inspection of small molded/metal parts—scratches, burrs, dents, flash, color mixups—prior to assembly.

Why It's Hard

Reflective metals and textured plastics produce unstable contrast; small flaws vary in appearance.

How Overview Solves It

Segmentation for pixel-accurate defect masks; filter by area/length.

Lighting + magnification dialed for metals/plastics.

Recommended cameras: OV80i for micro-defects and shiny parts; OV20i for general surface checks.

Proven in Production

Our precision work on small, reflective surgical parts validated at 100% accuracy prior to production ramp. Magnification + coaxial lighting caught micro-scratches that traditional systems missed.

Frequently Asked Questions

How small can the defects be?

With the OV80i and appropriate magnification, we've successfully detected scratches under 0.1mm in production environments.

What lighting setup works best?

Coaxial (on-axis) lighting works well for shiny metals; diffuse dome lighting for textured plastics. We can help you spec the right configuration.

Can it distinguish scratches from mold lines?

Yes. Train the model on examples of acceptable mold lines and true defects. The model learns texture and orientation patterns that distinguish the two.
