Abstract
Configurations and compositions for frameworks supporting optics such as lenses are described that provide an invariant structure regardless of temperature swings, thereby maintaining alignment and focus. Frameworks may comprise tiered structures of materials having multiple distinct coefficients of thermal expansion. An optical framework includes a first framework portion coupled to a first lens and a second framework portion coupled to a second lens. The first framework portion and second framework portion comprise materials having a coefficient of thermal expansion such that expansion of the first framework portion in one direction is offset by expansion of the second framework portion in an opposite direction.
