Optical Asphere Metrology

Metrology is a vital component of the asphere fabrication process and it must not be overlooked when determining fabricator capability. The ability to characterize aspheric form helps determine potential lens performance and enables subsequent deterministic correction. Asphere metrology has distinct challenges, but there are more options today than ever before.

This webinar explores specifying and tolerancing aspheric forms, today’s options for measuring aspheric form error, and how aspheric form determines manufacturing methods as well as influencing metrology selection.
