Laser profilometers are designed for high accuracy non-contact measurement of surface topography profile, form and texture measurement over large areas. It measures surface topography in the range 10's of millimeters to sub-micrometers, over area's up to 500mm x 500mm. The application of this system includes large area roughness measurement, surface digitization for mould texturing, in-tray inspection, and any other application that requires fast, large area, accurate surface profiling.
