The characteristics and applications of 3D optical profilometer
3D optical profilometer is commonly used to measure the surface roughness and contour morphology of the measured area in a sample. This article takes a 3D optical profilometer provided by Unicon Technology Co., Ltd. as an example, let's take a look.
Product Features:
Optical profilometer measures and analyzes the surface morphology characteristics of various products, components, and materials, including roughness, waviness, surface profile, surface defects, wear, corrosion, pore gaps, step height, bending deformation, and processing conditions.
Application:
Due to the limitations of processing equipment, traditional mechanical parts typically have precision requirements, including flatness and roughness, at the micrometer level. But with the development of technology, people's requirements for machining accuracy of mechanical parts have begun to move towards the nanometer level. The improvement of equipment machining 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, precision, reliability, and stability have begun to attract the attention of processing professionals and are being applied. 3D optical profilometers have been widely used in automotive engine fuel injectors, semiconductor cutting tools, artificial joint manufacturing, and gauge calibration. Some specific functions such as flatness, roughness, straightness, and height difference have shown new applications in mechanical processing inspection.
The Profilm3D optical profiler provided by Unicon Technology Co., Ltd. uses vertical scanning interferometry (VSI) combined with high-precision phase-shifting interferometry (PSI) measurement.
