These translation stages are flexure-constrained to provide linear or arcuate motions in one or more degrees of freedom with high degrees of precision and repeatability. With MechBlocks you can modify the mechanism to fit your needs perfectly by configuring its size, range, or even principle of operation. Contact us for more details on designing and building flexure devices.

Features 1-axis translation of 7 mm that is slightly arcuate but highly repeatable. For more range, compound or more compliant springs can be used. The top platform stays parallel to the bottom platform throughout its translation.

This translation stage is similar to the compound linear translation stage, except ‘folded’ into a more compact unit. It provides 15 mm of linear, smooth-continuous motion that is easily accessable via the top 5 x 5 block.

This device features a soft-spring stage, consisting of two springs, and hard-spring stage, consisting of 18 springs, creating an attenuation analogous to a voltage divider. This mechanism has an attenuation ratio of 9-to-1, enabling ultra-fine, subnanometer resolution movements.

The compound linear translation stage uses two nested four-bar stages to produce 15 mm of ultra-linear motion. The design enables the arcuate motion of the inner four-bar stage to be compensated by the equal and opposite arcuate motion of the outer four-bar stage.

The two-axis translation stage is comprised of a four-bar translation stage with an added stage to produce movement in a second, orthogonal axis. Both axes have 7 mm of range in a slight arcuate trajectory that is both repeatable and predictable from theory.

The double compound translation stage features linear translation with an open framed moving platform. This mechanism is designed to have exact constraint (i.e. not over or under constrained) enabling both high-repeatability and a 15 mm translation range.

The Nanoadjust works by using an actuator to deflect a lever horizontally, causing the the top-most 5 x 5 block to deflect vertically with an adjustable attenuation ratio (1-to-5 shown here). This enables nanometer resolution with a typical range of a few millimeters.

The twin compound translation stage has two stages, each one constrained to a single linear degree of freedom. The micrometer is fastened to one of the stages and provides force against the second stage enabling around 6 mm of differential motion.
