Assembly of components having different coefficients of thermal expansion

A component assembly includes a first component, such as an optical component, and a second component, such as a support component, having different coefficients of thermal expansion (CTEs). The component assembly also includes a spacer having a CTE matched to that of the first component, disposed b...

More Information
Summary:A component assembly includes a first component, such as an optical component, and a second component, such as a support component, having different coefficients of thermal expansion (CTEs). The component assembly also includes a spacer having a CTE matched to that of the first component, disposed between the first component and the second component. When the CTE of the first component is greater than that of the second component, the second component includes a protrusion, and the spacer includes a complementary opening for receiving the protrusion, such that a joint between the protrusion and the complementary opening is under compressive stress. The spacer also includes a mounting area for receiving the first component, and an air gap disposed between the first component and the protrusion.
