Novacam Profilometer system, for metrology and surface roughness inspection

Novacam's 3D Non-Contact Coordinate Measuring Machines are designed with versatility and superior performance in mind:

-Precision (better than 1um)
-Speed (1-30 thousand measurements per second)

Using a fiber-based optical profilometer NASA measures the thickness of liquid nitrogen in cryogenic chambers at its Propulsion Systems lab because these profilometers use fiber-based probes which can withstands the extreme environment, can be located hundreds of meters away from the interferometer and fit in the tight chamber which standard full-field profilometers with a human operator could not. The signal quality stays constant over the distance.
