Paper Abstract

We explain a new lens mounting scheme using cascaded ring flexures for minimizing thermal stresses. Two circular rings are concentric at the adhesive insertion hole and made monolithically on a lens cell. Six degree-of-freedom motions can be accommodated by controlling dimensional parameters. Thermo-elastic deformations are evaluated by interferometric measurements and are verified with finite element analyses. Athermal performances from a simple elastomeric mount and a ring-flexured mount are also compared. This lens mounting scheme was successfully applied to our space-borne optical system and will be a promising candidate for environmentally challenged optical systems such as military applications.
