Paper Abstract

Design of mechanical features such as spacers, retainers and/or cell shoulders used to locate and constrain lens components within a mount entails application of geometric relationships that depend upon the types of glass-to-metal interfaces to be provided. This paper describes the pertinent geometry of the most common surface-contact interface types (`sharp corner', spherical, tangential and toroidal) and gives equations for locating key features of the mechanical parts relative to the associated lens vertices. Examples illustrate the use of these equations to dimension mechanical features in typical lens/mount configurations.
