Determine the thickness measurement of technical glasses: The ultimate solution for non-contact thickness measurement of technical glasses

FOGALE nanotech's Low Coherence Interferometric Sensor (LISE) relies on the measurement technique of low coherence interferometry, also referred to as partial coherence interferometry. By comparing the optical paths in the glass with the optical path in an internal delay line, the system allows to measure the positions and thicknesses of glass layers and interlayer products.

All surfaces are detected in one measurement run in a few seconds. LISE reaches an absolute accuracy on air gaps and glass thicknesses of ±1 µm over a full measurement range of 200 mm (optical thickness).
