Closing the gaps in the precision asphere manufacturing process makes them an attractive solution for novel optical designs

摘要

Advances in asphere fabrication have led to their increasing use in optical system design. Even so, there is still substantial growth opportunity for aspheric technology for low-to-medium volume precision optics that operate in the visible or shorter wavelengths. This represents a sizeable portion of the optical industry and today, most optics that fall into this quality class consist almost exclusively of spherical surfaces. The main reason preventing their widespread use is that three gaps in the fabrication process remain.
