Fabricating and Testing Freeform Optics

Current Capabilities, Lessons Learned and Future Opportunities

Freeform optical shapes or optical surfaces that are designed with non-symmetric features are gaining popularity with lens designers and optical system integrators. A common question about freeform optics is, “If I design it, can you really make it?” This paper will overview a freeform optical fabrication process that includes generation, high speed VIBE polishing, sub-aperture figure correction, surface smoothing and testing of freeform surfaces.
