Fig. 11From: Quantitative coating thickness determination using a coefficient-independent hyperspectral scattering modelTwo regions in (a) are used to test the success of using the average slope in the 560–580 nm range (b and d) and the ratio between maximum slope value and the wavelength at this maximum (c and e). All thickness maps are very similar, but the map created from the maximum slope divided by the wavelength at this maximum is coarser. The thickness of all plots is given in μmBack to article page
