Thorough inspection workflows guarantee that manufactured parts meet the specifications needed for telecom, lithography, and laser systems.
Advanced tolerancing strategies for complex freeform geometries
Delivering intended optical behavior with asymmetric surfaces requires careful tolerance budgeting. Traditional, classical, conventional tolerance methodologies often struggle to adequately describe, model, and represent the intricate shape variations inherent in these designs. Accordingly, tolerance engineering must move to metrics like RMS wavefront, MTF, and PSF-based criteria to drive specifications.
Concrete methods translate geometric variations into wavefront maps and establish acceptable performance envelopes. Applying these tolerancing methods allows optimization of process parameters to reliably achieve optical specifications.
