Metrology
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
- Fisba interferometry with white light system for surface analysis
- High homogeneity testing
- Refractive index testing
- Stitching interferometry
- Material strain testing
- Non-contact measurement
- Environmental testing
- Temperature and humidity testing
- Mechanical inspection
- Shadowgraph
- External coating testing, where required
