The features and applications of 3D optical profilometers

3D optical profilometers are often used to measure the surface roughness and contour morphology of the measured area in samples. This article takes a 3D optical profilometer provided by Unicon Technology Co., Ltd. as an example. Let's take a look.

Product features

The optical profilometer measures and analyzes the surface topography features of various products, components and materials, such as surface profile, roughness, waviness, surface shape profile, surface defects, wear conditions, corrosion conditions, pore gap, step height, bending deformation conditions and processing conditions.

Application

Due to the limitations of processing equipment, the precision requirements for traditional mechanical parts, including flatness and roughness, usually remain at the micrometer level. However, with the development of technology, people's requirements for the processing accuracy of mechanical parts have begun to move towards the nanometer level. The improvement of equipment processing accuracy has driven the development of detection technology. Traditional detection methods, including contact and 2D methods, have significant limitations in detecting mechanical parts with nanometer level accuracy.

When optical profilometers are applied in the optical processing industry, their 3D, high-speed, precise, reliable and stable features have begun to attract the attention of processing professionals and have started to be used. 3D optical profilometers have been widely applied in areas such as automotive engine fuel injectors, semiconductor cutting tools, artificial joint manufacturing, and gauge block calibration. Some specific functions such as flatness, roughness, straightness and height difference have shown new applications in mechanical processing inspection.

The Profilm3D optical profilometer provided by Unicon Technology Co., Ltd. employs vertical scanning interferometry (VSI) combined with high-precision phase shift interferometry (PSI) measurement.
