Athermal Lens Mount with Ring Flexures

다국어 초록 (Multilingual Abstract)

We present a new athermal lens mounting scheme made of cascaded ring flexures. Two circular grooves are concentric at the adhesive injection hole and are fabricated monolithically on the lens cell or the barrel itself. The ring flexure can accommodate six-degree-of-freedom motions by controlling dimensional parameters. We evaluate thermo-elastic deformations by using interferometric measurements and verify the results with finite element analyses. Also, we compare the athermal performances from a simple elastomeric mount and a ring-flexured mount. This lens mounting scheme should be a promising candidate for environmentally-challenging optical systems like those used in space and military applications.
