Tailored surface geometries enable focused control over distortion, focus, and illumination uniformity. Custom topographies enable designers to target image quality metrics across the field and wavelength band. As a result, freeform-enabled imaging solutions meet needs across scientific, industrial, and consumer markets. Iterative design and fabrication alignment yield imaging modules with refined performance across use cases. Their capacity to meet mixed requirements makes them attractive for productization in consumer, industrial, and research markets.
Real-world advantages of freeform designs are manifesting in improved imaging and system efficiency. Accurate light directing improves sharpness, increases signal fidelity, and diminishes background artifacts.

Advanced assessment and inspection methods for asymmetric surfaces
Freeform optics, characterized by their non-spherical surfaces, pose unique challenges in metrology and inspection. Achieving precise characterization of these complex geometries requires, demands, and necessitates innovative techniques that go beyond conventional methods. Optical profilometry, interferometry, and scanning probe microscopy are frequently employed to map the surface topography with high accuracy. Advanced computation supports conversion of interferometric phase maps and profilometry scans into precise 3D geometry. Comprehensive quality control preserves optical performance in systems used for communications, manufacturing, and scientific instrumentation.
Performance-oriented tolerancing for freeform optical assemblies
High-performance freeform systems necessitate disciplined tolerance planning and execution. Traditional tolerance approaches are often insufficient to quantify the impact of complex shape variations on optics. So, tolerance strategies should incorporate system-level modeling and sensitivity analysis to manage deviations.
Approaches typically combine optical simulation with statistical tolerance stacking to produce specification limits. Integrating performance-based limits into manufacturing controls improves yield and guarantees system-level acceptability.
