Abstract

Optical designs often specify both surface form and centering (tilt and lateral displacement) tolerances on aspheric surfaces. Such tolerances are often ambiguous and current standards do not resolve this ambiguity. We describe several difficult issues that arise in attempting to interpret aspheric centering tolerances and their consequences for optical design and metrology. We conclude by calling on the optics community to standardize an interpretation method for aspheric tolerances.
