Abstract
This compound linear flexure bearing incorporates a simple but unique flexure arrangement which inherently allows stable long travel operation. The flexure arrangement passively constrains all degrees of freedom except translation along the bearing axis while also compensating for flexure foreshortening. This design permits large displacement, low operating stress, low operating force, and high stiffness in the five noncompliant degrees of freedom. The linear flexure bearing described herein has applications in precision mechanics, particularly opto-mechanics. Specific applications include but are not limited to wafer and reticle positioning stages used in microlithography systems, optic translation and scanning mechanisms used in tactical and spaceborne systems, as well as flip-in mechanisms used in multiple field of view optical systems.
