A typical, but still challenging application of compliant mechanisms with flexure hinges are lens manipulators. Especially in high precision optical systems those are common means to correct optical imaging errors. The requirements for lens manipulators with respect to the resolution of motion are in the order of nanometres and nanoradians. The kinematic concepts and embodiment considerations of manipulators are proprietary knowledge of the companies using them and there is almost no literature about general design considerations available. However, general kinematic principles can be found in patents and used to compare their underlying compliant mechanisms. Therefore, this paper presents a survey of certain kinematic manipulator concepts based on existing patents. The resolution and range of motion of the manipulators are estimated and put into perspective in the context of lens manipulation. The comparison of identified kinematic concepts is used to emphasize aspects of practical implementation and embodiment design of flexure hinges in lens manipulators. The findings are discussed with respect to the bending-torsion-stiffness ratio of flexure hinges and compliant mechanisms.
