Paper Abstract

To enable the invention of new optical instruments subjected to a broad range of operating conditions, there is a need to develop improved technology to hold small mirrors and other optical elements with high dimensional stability and low cost. A previous paper described a screening experiment on small face bonded mirrors subjected to an environment of -41 to +70 degree(s)C with the intent of finding factors that influence the bond joint's contribution to angular stability. This paper describes part of the continuing experiment, specifically addressing BK-7 mirrors bonded to Aluminum mounts with a flexible adhesive. The resulting tilt errors in the mirror assemblies were measured, and showed a definite pattern with respect to bond thickness. Flexible bonds between these two CTE mismatched materials did not fail, and exhibited high stability over temperature at 0.002-inch bond thickness.
