Optical Coherence Tomography Profilometer System

Across industries

The list below presents typical metrology solutions by industry. Due to limited space and since new applications of low-coherence interferometry are discovered daily, this list is not exhaustive and requires periodic updates. If you do not see your industry or application listed, we encourage you to contact us and we’ll be happy to discuss your particular metrology needs.
