Precision metrology approaches for non-spherical surfaces
Freeform optics, characterized by their non-spherical surfaces, pose unique challenges in metrology and inspection. Precise characterization leverages multi-modal inspection to capture both form and texture across the surface. Optical profilometry, interferometry, and scanning probe microscopy are frequently employed to map the surface topography with high accuracy. 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.
Optical tolerancing and tolerance engineering for complex freeform surfaces
Delivering intended optical behavior with asymmetric surfaces requires careful tolerance budgeting. Classical scalar tolerancing falls short when applied to complex surface forms with field-dependent effects. So, tolerance strategies should incorporate system-level modeling and sensitivity analysis to manage deviations.
In practice, modern tolerancing expresses limits via wavefront RMS, Strehl ratio, MTF thresholds, and related metrics. Utilizing simulation-led tolerancing helps manufacturers tune processes and assembly to meet final optical targets.
