White Light Interferometry

metuWLI

Our metuWLI White Light interferometer enables fast, non-contact measurement and surface characterization at the micro- and nanometer scale, making it ideal for robust quality control and inline process monitoring.

To fit your specific manufacturing setup, the sensor is available either as a compact benchtop system or as an integrated sensor head for inline and in-situ applications. We also offer tailored configurations to ensure reliable measurements in high-vibration environments.
