The S-312 is a series of piezo phase shifter stages designed for optical phase-shifting applications in interferometers and optical circuits, utilizing three open-loop PICMA® piezo actuators driven by an analog voltage (0-100 V) to achieve up to 15 µm linear travel with sub-nanometer resolution. Available in five clear apertures from 53 mm to 311 mm, the stages have a low profile starting at 28 mm and are constructed of aluminum with a mass range of 1.8 kg to 2.5 kg depending on size. The stages support Z-motion with optional tip/tilt correction, feature a 0.5 m cable with pigtail or LEMO connector options, operate from -20 °C to +80 °C, and are compatible with the E-836 or E-663 amplifiers. Their natural frequency ranges from 45 Hz to 560 Hz depending on payload and size.
The S-312 piezo stages are designed for optical phase-shifting applications, where nanometer-level motion alters the phase of light waves traveling through a lens mounted on the stage. These stages are typically integrated into interferometers but are also suitable for use in a variety of optical circuits. Thanks to their high-stiffness design, they enable sub-nanometer steps with millisecond response times-ideal for rapid fringe shifting.
