Quick Vision WLI Series, vision measuring instruments, from Mitutoyo, combine vision systems with white light interferometers (WLI) . Quick Vision model HYPER WLI has a white light interference sensor which is capable of acquiring surface areas at a very high resolution in a single movement of the instrument.
It is thus possible to recognize microstructures and microgeometries on the surface of the workpiece and evaluate them from a measuring standpoint, even an accuracy of measurement in the area of a few nanometres can be achieved on smooth surfaces.
Compared with white light interferometers as stand-alone solutions, Mitutoyo's combination with a vision measuring instrument has considerably advantages. For example,it is possible to determine and move to the image recording position very precisely. and it is easily possible to then combine individually recorded images or point clouds.
