Piezo-Assist Linear Stages

Piezo-Assist Linear Stages are manual linear translation stages, equipped with a lead zirconate titanate (PZT) crystal which proportionally changes its static dimension when an external electric field is applied to it. The piezo adjustment is designed to be used in conjunction with the micrometer to extend the stage resolution from 10μm down to <20nm. The piezo element requires power to remain activated to hold its position. Piezo-assist motion is not audible. Controllers are available in 1- and 3-axis versions. These type of stages are frequently used in applications such as microscopy, metrology, optical fiber alignment, interferometry, or wherever submicron linear positioning is required. Industries that utilize linear stages include research, bio-medical, life sciences, astronomy, metrology, semiconductor, and more. They are available in 25, 40, and 60-millimeter platform sizes. They are configured for X, XY, and Z-axis linear translation. All of our stages are specifically designed to be stacked with other linear and rotation stages having the same size and mounting threads. If one of our many catalog piezo-assist stages does not meet your requirements, just send us a request for a custom version. OptoSigma is, after all, the industry leader in translation stages.
