Profiling and metrology solutions for complex surface optics
Irregular optical topographies require novel inspection strategies distinct from those used for spherical parts. Precise characterization leverages multi-modal inspection to capture both form and texture across the surface. Measurement toolsets typically feature interferometers, confocal profilers, and high-resolution scanning probes to capture form and finish. Robust data analysis is essential to translate raw measurements into reliable 3D reconstructions and quality metrics. Quality assurance ensures that bespoke surfaces perform properly in demanding contexts like data transmission, chip-making, and high-power lasers.
Performance-oriented tolerancing for freeform optical assemblies
Achieving optimal performance in optical systems with complex freeform surfaces demands stringent control over manufacturing tolerances. Traditional, classical, conventional tolerance methodologies often struggle to adequately describe, model, and represent the intricate shape variations inherent in these designs. So, tolerance strategies should incorporate system-level modeling and sensitivity analysis to manage deviations.
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.
