Abstract

Optical centering is the alignment of optical surfaces or elements with respect to a datum or datum system. The datum may either be a point, an axis, a surface, or a cylinder. The method of describing optical centering is unlike other sections of ISO 10110 because optical centering relies heavily on mechanical engineering methods and geometrical dimensioning and tolerancing (GD&T). ISO 10110-6 specifies surface tilts, surface decenters, runouts, and beam deviations that can be used to tolerance the centering of an optical surface, an optical element, or a subsystem.
