Paper Abstract

This paper applies analytical means previously published by Chen and Nelson (1979) to estimate the shear stresses developed within the joints between typical cemented optical components and within opto-mechanical subassemblies made of materials with significantly different coefficients of thermal expansion (CTEs) when exposed to extreme ambient temperatures. Two cemented doublet examples, one involving glasses with a large CTE mismatch and another with more equal CTEs, are analyzed. An example involving a prism made of fused silica bonded with epoxy to a titanium base also is considered.
