Product Summary of Dual Layer Coatings on Substrates

These are high purity, in almost all cases, single element films consisting of two separate layers, deposited on a solid, rigid, thick substrate. These standards are more robust and usually lower cost than corresponding foil standards but are generally applicable to one or a small set of coating thickness applications. Dual layer coating standards on substrates are used for calibration of XRF for simultaneous measurement of two layer thickness testing applications on samples with the same or similar substrates as the standards used to calibrate the XRF. If the substrate of the standard is not the same as the substrate of the sample being tested, please consult with your XRF provider before purchasing these standards. These standards are typically mounted in the same frames as foil standards exposing a limited area of the standard for measurement.
