ABSTRACT:
An athermalized beam source and collimator assembly includes a collimator lens spaced from a novel circular foldback flexure plate by a lens barrel. The circular foldback flexure plate incorporates a circular foldback flexure adjacent the beam source mount to isolate the beam source from the ambient environment and to athermalize the assembly. The beam source mount and circular foldback flexure plate are composed of a material that is identical in composition and CTE as the portion of the beam source that is attached to the beam source mount. The temperature of the beam source may then be maintained by a thermal element mounted to the back surface of the flexure plate, without the occurrence of mechanical strain at the interface between the beam source and beam source mount.
