The use of a laser and an infra-red sensor of Enovasense (now part of Precitec Optronik) allows a contactless thickness measurement for a coating analysis of semi-transparent and intransparent layers at a distance of 5 to 20cm.The laser heats very mildly the part to be analysed, so that neither the coating nor the main component are damaged or altered during the measurement processwhich takes not longer than a second.
