Abstract

This paper outlines methods for dimensioning and tolerancing lens seats that mate with spherical lens surfaces. The two types of seats investigated are sharp corner and tangent contact. The goal is to be able to identify which seat dimensions influence lens tilt and displacement and develop a quantifiable way to assign tolerances to those dimensions to meet tilt and displacement requirements. After looking at individual seats, methods are then applied to multiple lenses with examples. All geometric dimensioning and tolerancing is according to ASME Y14.5M - 1994.
