Mahr Federal’s MarSurf VM 100 and MarSurf CWM 100 optical surface measuring systems are designed to provide fast non-contact 3D scanning and evaluation of very small to medium sized surface details on a range of components, including optics. The WM 100 uses a white light interferometer and the CWM 100 includes both white light and confocal microscopy. The systems are designed for the measurement of optical, technical and reflecting surfaces, and to provide 3D topographical analysis where high information density is required, such as printed circuit boards.

The measuring systems provide highly accurate, non-contact measurement of surface structures with sub-nanometer resolution. Confocal microscopy is more adept at the measurement of dark surface structures, including the edges of small components, while white light interferometry is better suited to highly polished, shiny surfaces, including glass and optical surfaces.

The white light scanning sensor in both units is designed for fast-paced 3D roughness measurement, using real time video scanning technology for excellent, high-resolution reproduction of even microscopic surface details, the company says. It comes standard with a 20× lens, with others available ranging from 2.5× to 100×, and provides resolution down to 0.1 nm.

The confocal microscope available with the CWM 100 provides measurement of both 2D and 3D parameters to international standards along selectable surface lines or areal extracts. A 50× confocal lens is included, with others available. The CNC controlled object table and Z axis provide 100-mm traversing range.
