Fiber-based probe technology enables Novacam low-coherence profilometers to provide 3D metrology in harsh environments which can be:
|radioactive, very hot, or extremely cold (cryogenic)|
Inspecting with fiber-based probes
Novacam profilometers inspect with fiber-based non-contact probes. The probes:
Examples of applications
Very hot: Materials that are evaporating, melting, or solidifying can all be inspected with Novacam rugged non-contact probes. In industries that handle extremely hot liquids, such as red-hot steel, plasma, or metals in continuous casting, the sensor probes scan the surface in process and on a continuous basis, detecting micron-sized surface variations. Surface roughness or coating thickness characteristics are delivered at high speed to help detect defects such as minute surface cracks.
Radioactive: Low-coherence profilometers measure the pitting of radioactive targets and detect both surface and sub-surface cracks in weld inspection inside reactor cooling systems.
Cryogenic: Low-coherence profilometers measure the level of liquid nitrogen in NASA’s cryogenic chambers at its Propulsion Systems Lab.
Evaporation chambers: Low-coherence profilometers monitor the thickness of a semi-conductor or metal coating during the deposition process. In this way, the optimal stopping time of the coating process is determined.
