To deliver high quality components and systems, it is critical to accurately measure and test processed optical components with high precision and accuracy.

We have invested in world-class measurement equipment to ensure the parts our customers receive meet the most exacting of specifications.

We use a range of interferometric measurement systems during production and at the end of processes as part of our quality assurance procedures. This enables us to provide a broad range of exceptionally high-quality precision optical components and assemblies.

In addition to ongoing inspection results, we can provide further analytical support to clients through:

  • Capability studies (to calculate Cpk)
  • Failure Mode and Effects Analysis (FMEA)
  • Production Part Approval Process (PPAP)
  • Gauge R&R
  • SPC techniques
