Hard-to-reach spaces

Novacam low-coherence profilometers facilitate surface inspection and 3D metrology inside hard-to-reach spaces.

Small fiber-based non-contact probes reach inside to measure:

  • interiors of bores and small-aperture cylinders
  • interiors of fuel injectors
  • through-holes of connecting rods and camshafts
  • inside surfaces of blisks (bladed disks in the aeronautics industry)

with precision better than 1 µm. Novacam offers probes in a range of lengths and diameter sizes (as small as 0.9 mm). Probes are either side-viewing or front-viewing, and are typically used in concert with a suitable scanning mechanism. Rotational probes are also available.
