Precision metrology approaches for non-spherical surfaces
Freeform optics, characterized by their non-spherical surfaces, pose unique challenges in metrology and inspection. High-fidelity mapping uses advanced sensors and reconstruction algorithms to resolve the full topology. Common methods include white-light profilometry, phase-shifting interferometry, and tactile probe scanning for detailed maps. Data processing pipelines use point-cloud fusion, surface fitting, and wavefront reconstruction to derive final metrics. Sound metrology contributes to consistent production of optics suitable for sensitive applications in communications and fabrication.
Tolerance engineering and geometric definition for asymmetric optics
Stringent tolerance governance is critical to preserve optical quality in freeform assemblies. Conventional part-based tolerances do not map cleanly to wavefront and imaging performance for freeform optics. This necessitates a shift towards advanced optical tolerancing techniques that can effectively, accurately, and precisely quantify and manage the impact of manufacturing deviations on system performance.
These techniques set tolerances based on field-dependent MTF targets, wavefront slopes, or other optical figures of merit. Through careful integration of tolerancing into production, teams can reliably fabricate assemblies that meet design goals.
