profilometer

[‚prō·fə′läm·əd·ər]
(engineering)
An instrument for measuring the roughness of a surface by means of a diamond-pointed tracer arm attached to a coil in an electric field; movement of the arm across the surface induces a current proportional to surface roughness.

Alicona IFM G4 is using to analyze 540 irradiated crater depths to obtain the optical surface micrograph and its corresponding profilometer graph.
A stylus profilometer was preferred because it was capable of measuring the profile over the entire length of the ramp in one measurement.
After the tests, the cross-sections of the wear scars were studied applying the Mahr profilometer, and the respective wear volumes were calculated as a product of the cross-section area of the wear scar by its length; average wear volumes were calculated afterwards.
We measured the surface roughness of alfalfa, broccoli, and radish seeds with a confocal laser scanning microscopy (CLSM) method developed in our laboratory and validated the results with a contact surface profilometer.
