Abstract
A window structure includes a housing, a window received into the housing, and a mounting support joining the window to the housing. The mounting support has an outer support ring joined to the housing, where the outer support ring has a coefficient of thermal expansion of about that of the housing, and an inner support ring joined to the window, where the inner support ring has a coefficient of thermal expansion of about that of the window. The inner support ring is joined to the outer support ring by a single-segment or multi-segment ring with a gradation in thermal expansion coefficient, but is not radially aligned with the outer support ring. The result is a large reduction in the stresses and strains otherwise imposed on the window.
