Description
Summary:As an ideal starting point, the specimen should have an analytical depth for each wavelength (energy) analyzed that provides infinite thickness. That is, the thickness of the sample will not affect the analysis. On a more practical note, the specimen should have an effective layer thickness that will provide at least 99% of the analysis. Figure 3 shows the concepts of infinite thickness and effective layer thickness. The wavelengths of interest are not excited in the white layer.
