Unlike most common profilometers this device can be used to measure the thickness profile of samples having both surfaces irregular. A sensitivity of about 0.2 mm, independent of the sample thickness is achieved.application/pdfengDifferential profilometerThickness measurementA differential mechanical profilometer for thickness measurementjournal article
