​OF&T will offer new ideas and concepts for the shaping, smoothing, testing and manufacture of conventional and novel optics/optical systems finding applications in existing and emerging technologies.

The 2021 Optical Fabrication and Testing Topical Meeting (OF&T) will emphasize new ideas, concepts and emerging applications in optics manufacturing and metrology. Hot topics will include the following: fabrication of optics by lasers, additive manufacturing of optical components, molding of micro-optics, deterministic manufacturing of aspheric/conformal/freeform optics, advanced metrology systems and direct slope/curvature measurement, fabrication of optics from novel materials, efficient manufacturing and testing of large optics, new CNC machining processes and advances in finishing science. Papers that describe manufacturing chains from the generation of complex shapes to the fine finishing of surfaces, giving details of the process science, will be especially welcomed.
