aspheres, measuring aspheres, optical metrology, measuring aspheres in 3d

 

This white paper provides an essential practical guide on the benefits of 3-D measurements of aspheres as well as a couple of real-world examples of parts that we have manufactured. This white paper also goes into detail why one may prefer measuring aspheres in 3-D over 2-D, not to review the merits of the individual technologies as they apply to specific shapes. Also, we will distinguish the difference between measuring aspheres in 2-D (form) and 3-D (irregularity).

 

Measuring Aspheres in a 3-D World White Paper
 
 
 

This chart will explain our spherical and aspherical tolerance limits.  This chart also provides materials we use, diameter range, coatings, lead time, core competencies, ideal quantities, and our top 10 Asphere design tips.  This chart can be beneficial to our customers and potential new customers to know what our manufacturing limits are when specifying their optical components.
