CouPhysik Instrumente’s (PI) N-565 compact nanometer-precision linear stages are designed for high-end applications in bio-nanotechnology, fiber-optics, microscopy, semiconductor testing, and metrology and scientific research in beamlines and laser labs. Travel ranges 1/2-, 1- and 2-in. are offered in 13, 26 or 52 mm. An integrated interferometric linear encoder developed by PI can resolve to 20 pm and allows incremental motion below one nanometer. The N-565 features PiezoWalk technology, which combines the technological advantages of piezo class resolution with long travel ranges. They offer subnanometer resolution and are not subject to sliding friction effects. Preloading the actuators against the runner ensures a self-clamping force even when powered down and the piezo stepping drive holds a position mechanically stable without servo jitter and energy consumption. With crossed roller bearings, the point contact in ball bearings is replaced by a line contact of the hardened rollers.
