The company adds the MarSurf WS 1 to its offerings in the field of optical surface metrology. Using white light interferometry in a compact design, the system provides vertical resolution of 0.004 microinch (0.1 nm) and 3D measurement in seconds, the company says. With the MarSurf XT 20 topographical evaluation software, the system can be configured to work both in the lab and on the shop floor. The white light optical sensor is designed to enable rapid, high-precision recording of surface topography on a wide range of materials. Using white light and a CCD camera, the system can collect height information through the camera's field of view. The camera simultaneously images both the test surface area and a high-precision reference surface built into the objective lens.
