Applications by industry

The list below presents our typical metrology solutions by industry.  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.
