Abstract
A flexure/actuator is configured to reliably provide motion reduction, e.g. for positioning or adjusting telescope or other technical or scientific instrument components, preferably at cryogenic as well as higher temperatures. The flexure can be constructed to provide support and strength, preferably in all axes, such as may be needed to withstand launch forces. Preferably flexure axes are defined at upper and lower edges of sidewalls and at intermediate positions of sidewalls. Actuator activation adjusts distance between sidewall intermediate flexures and, by operation of sidewall flexures, adjusts the distance between upper and lower surfaces with a desired reduction ratio.
