This chart will explain the manufacturing tolerance limits with regard to surface, dimensional, and aspheric tolerances. This chart also provides various measurements for standard, precision, and high precision attributes. We include materials, diameter range, coatings, lead time, core competencies, and the ideal quantities in this chart as well. Also, included is an asphere guide that explains the metrology, diameter, form error, and slop error tolerances. This can help customers with their specifications when providing prints to our engineer's.
