A profilometer is an instrument that measures a surface profile to determine its roughness. A surface’s vertical resolution is normally measured at the nanometer level, with lateral resolutions being measured to a less accurate degree. Over the past decade, profilometers have started using laser te...
Most micro-scratches produced with small micron aluminum oxide abrasive will be less than .000001” (.025 micron) deep and can’t usually be measured with a profilometer. Micro-scratches should not be confused with deeper scratches produced by particles of contamination or other causes....
Roughness measurements, however, utilize profilometers or atomic force microscopy, focusing on the microscopic details of surface texture. 8 The control of flatness and roughness is essential for optimizing the performance and lifespan of mechanical components. Adjustments in manufacturing processes, such ...

A. The English language is a SOB sometimes. OK let me see if I understand what you are looking for. The length of the part is one thing. the length of the profilometer stroke is another, the reading of the surface finish is the 3rd thing. So if I understand this right, you are ...
Because of their shapes, aspheric surfaces typically cannot be measured using exactly the same techniques employed with spherical surfaces. The simplest and least expensive method for gauging aspheric surface shape is with the use of a contact profilometer. These instruments operate by drawing a small...
Malleability is applicable in both scientific endeavors and everyday life. For example, malleability in metals accounts for virtually every part within an automobile, especially in the chassis and engine. A metal’s malleability allows it to be used to construct kitchen appliances such as refrigerator...
2.4. Optical Profilometry The surface roughness was tested with the Contour GT optical profilometer from (Bruker, Karlsruhe, Germany). This method uses a laser beam, which gives non-contact and non-invasive measurements. They are based on the measurement of the distance between the white light ...
