Abstract

This paper offers guidance to design engineers on the safe mounting of optical mirrors using elastomeric adhesives. Elastomeric adhesives are attractive because they isolate mirrors from the strains and deflections of the structural attachments in the instrument: The elastomers provide an effective buffer between them. Unfortunately the elastomers also couple the mirrors to mounts of, usually, differing thermal expansion properties. The design of the adhesive bond joints must balance the stiffness of the mirrors, the properties of the elastomers and the differences in CTE between the mirrors and their mounts. The engineer is guided, by this paper, in the design of the elastomeric adhesive bond.
