3D Optical Surface Measuring Systems
The MarSurf CWM 100 and WM 100 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. It comes standard with a 20x lens, with others available ranging from 2.5x to 100x, 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 50x confocal lens is included, with others available. The CNC controlled object table and Z-axis provide 100 mm traversing range. Measurement and evaluation are provided by easy-to-use Mountains for Mahr software, which allows surface views as profile section diagrams, topography, or 3D microscopy. Data can be imported and exported in differing formats, and the MarSurf aspheric option allows fast analysis of spherical and aspherical lenses.
