Ultra-stable isostatic bonded optical mount design for harsh environments

摘要

Through the years many stable optical mounts have been designed, analyzed and tested at TNO. This paper gives anoverview of the design principles used. Various examples are presented together with verification test results.The use of adhesives in combination with an iso-static mount design allows mounting of optical components in a limitedvolume with limited deformation of the optical surfaces due to thermal and mechanical loads. Relatively largedifferences in thermal expansion over large temperature ranges can be overcome using a simple and predictable design atreasonable costs. Despite adhesives have limited dimensional stability and loadability, stable optical mounts can berealized when proper design principles are used.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
