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.
Long Range Sensor for large Measuring Distances
The optoNCDT 1760-1000 long-range laser sensor by Micro-Epsilon also measures at distances of up to 2m with up to 7.5kHz.
