Free-standing thin membranes are used in numerous scientific and industrial contexts. The thickness of these membranes is often highly relevant for their pertinent function. PTB's new measurement device allows a quick and very accurate determination of the membrane thickness. For this purpose, the membrane is contacted from both sides. By integrating two fiber interferometers into the microelectromechanical system (MEMS), low uncertainties can be attained. (Technology Offer 0361)
