Therefore, thickness determination is a significant parameter that has to bemonitored during the automotive painting process. In this application note, measurements of clear coat paintlayer thickness in different spots of a used car are being demonstrated using ThetaMetrisis FR-Tools. Means & Methods:The thickness of clear coat paint layer was measured inthe 850 -1700nm spectral regime, using FR-Series product. In order toidentify the uniformity of the paint thickness, measurements were made atdifferent points of a used car. The measurement set-up is shown in the imageat the right. Results:Measurements were performed on top and on the door of the car. The fitting was applied in the 1400-1600 nm spectral range. Reflectance and fitted spectra and the calculated thicknesses are illustrated in theimages below. The thickness on top measured at point 1 = 41.6um and at point 2 = 39.8um and on the doormeasured at point 1 = 45um and at point 2 = 44.9um. FR-tools in that particular spectral range could beemployed for non-destructive fast & accurate measurement of the thickness of that layer and contributesignificantly in qualityassurance. 就 lastar) EE一 HHE Figure 1: Reflectance and fitted spectra from theclear coat on top of the car at point 1.
