The Helmut Fischer XRF Film Thickness Measurement XDV®-SDD is one of the most powerful X-ray fluorescence analyzers in the Fischer portfolio for Film Thickness Measurement. This XRF spectrometer is equipped with a particularly sensitive silicon drift detector (SDD). This allows you to measure even the thinnest layers non-destructively – e.g. gold coatings about 2 nm thick on lead frames. 

At the same time, the XDV-SDD is perfectly suited for non-destructive material analysis. For example, its detection sensitivity for traces of lead in plastic is about 2 ppm – several orders of magnitude lower than the values required by RoHS or CPSIA.

So that you can create the ideal conditions for each XRF film thickness measurement, the XDV-SDD has exchangeable collimators and primary filters, which allows work on a scientific level. The extremely robust device is nonetheless easy to operate and is designed specifically for series tests in industrial use. Features like its automatically extending measuring stage and the live image of the measuring site make your day-to-day work easier.
