Precision Aspheres: Manufacturing and Metrology - LaCroix Precision Optics

Aspheres have allowed optical designers to create systems and products that push the limitations of performance across several fields. In this presentation, we will explain the various processes utilized to manufacture precision aspheres. Our presentation will apply to grinding and polishing aspheres, as well as the metrology utilized to verify important specifications such as form error, slope error, and surface roughness. This will assist optical designers in understanding the common challenges in regards to aspheric manufacturing.
