Coordinate Measurement Machine (CMM)
A coordinate measuring machine (CMM) provides precise measurement of the dimensions and geometry of physical objects. A probe or sensor detects points on the object’s surface, and the 3D position of each point is recorded. From this point cloud, the object’s features can be mapped in relatively high resolution, and dimensions can be extracted for product design, quality…

Phase-shifting Interferometer
A phase measuring interferometer detects the difference in phase between the test and reference legs of a split laser source, enabling measurement of surface deviations on the nanometer scale. Phase data can be acquired by physically changing the path length of one of the interferometer arms between each measurement. The data can also be acquired…

Confocal Microscopy
Confocal microscopy is a technique for measuring surface texture and shape. In a confocal microscope, pinhole aperture is used to create a single focus point and to reject out-of-focus light, which enhances image resolution and contrast. An image is formed by scanning a laser source across the sample, generating a 2D image. These images are stacked…

Prof. Von Weingraber
Prof. Von Weingraber A Surface Metrology Pioneer. Professor Von Weingraber from Hannover Germany is recognized in the field of surface metrology for his significant contributions to the development of methods for analyzing and characterizing surface topography, particularly by advocating for the concept of an “envelope” to link surface metrology with dimensional metrology, allowing for a…
