Nanometer Thickness Measurement for Films The IMS5400-TH white light interferometer is used for highly accurate thickness measurements from a relatively large distance. A decisive advantage here is the distance-independent measurement, where a nanometer-accurate thickness value is achieved even with moving objects. The large thickness measuring range allows the measurement of thin layers, flat glass and films. Since the white light interferometer works with an SLED in the near infrared range, thickness measurement of anti-reflective... (read more)Browse Interferometers Datasheets for Micro-Epsilon Group -
