Working principle and application of 3D optical surface profilometer
Why is it necessary to measure surface morphology?
In production, the micro surface morphology has a direct impact on the evaluation of many technical properties of engineering parts, and the three-dimensional evaluation parameters of the surface are increasingly valued for their ability to comprehensively and truly reflect the characteristics of the part surface and measure the quality of the surface. Therefore, the measurement of the three-dimensional micro morphology of the surface is crucial. By measuring the three-dimensional morphology, the quality of the surface can be comprehensively evaluated, and the quality of the processing method and the rationality of the design requirements can be confirmed. This can then be used to guide the processing and optimize the processing technology to produce a high-quality surface, ensuring the realization of the functional use of the parts.
The measurement principle of 3D optical surface profilometer:
The light emitted by the light source is collimated and then split into two beams by a beam splitter prism. One beam is reflected back from the surface being measured, while the other beam is reflected by a reference mirror. The two reflected beams converge and interfere. The microscope converts the morphological characteristics of the surface being measured into interference fringe signals, and measures the three-dimensional morphology of the surface by measuring the changes in the interference fringes.
Application of 3D Optical Surface Proformer
The Profilm3D optical profiler provided by Unicon Technology Co., Ltd. is suitable for measuring and analyzing surface morphology features such as flatness, roughness, waviness, surface profile, surface defects, wear, corrosion, pore gaps, step height, bending deformation, and processing of various products, components, and materials.
