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.
