Thermal compensating mount

摘要

A thermal compensating mount 10 is provided for an alignment sensitive component 12. Thermal compensating 10 mount comprises a cylindrical extension 14 which is formed integral to and has the same coefficient of thermal expansion as alignment sensitive component 12. A cylindrical receptacle 20 is formed into mounting surface 18. Cylindrical extension 14 secured within cylindrical receptacle 20 that surrounds the cylindrical extension. The difference between the diameter of cylindrical extension 14 and cylindrical receptacle 20 is such that the differential thermal expansion across cylindrical extension 14 and the edges of cylindrical receptacle 20 is exactly compensated for by the thermal expansion of the surrounding adhesive 16.
