Metrology At Work

Bel Air can provide you with an ideal non-contact metrology unit for accurate surface measurements. These units are small and compact and includes all software required for use. The units are ready for use out of the box, and will provide 2D, 3D and live images of your parts. Bel Air will help you choose the best of several units, best suited for your needs.

Bel Air Finishing now offers a Surface Metrology Service utilizing non-contact white light interferometry technology.This technology offers many benefits over single line surface metrology technology such as stylus type profilometers;

  1. Roughness over an area.
  2. Roughness on parts with complex geometry (convex, concave, etc.)
  3. Properties of the surface finish (direction & depth of finish ect.)
  4. 3D View of a defect (helps identify the cause)
  5. And much more...

Send us a picture of your parts, and we will provide a range estimate for your review.
