Product overview
S-312 piezo phase shifters are precision nanopositioning stages engineered for optical phase shifting in advanced interferometry applications. Providing smooth motion with subnanometer resolution and millisecond responsiveness, these stages enable precise shifting of interference fringes for phase analysis. Typically integrated into interferometers but also suitable for other optical applications, the S-312 piezo stages are ideal for both research and industrial metrology.
Operation
The compact tripod piezo-drive design incorporates three long-life PICMA® piezo actuators, spaced at 120° intervals. When controlled jointly, they provide linear motion along the optical axis. Individual control is also possible for tip/tilt error correction or bias adjustment. The combination of responsiveness, resolution, and reliability makes the S-312 optical phase shifters a robust solution for demanding optical measurement and phase-shifting interferometry tasks.
Models and aperture sizes
The S-312 family includes five clear-aperture sizes:
- Ø 53 mm
- Ø 108 mm
- Ø 158 mm
- Ø 208 mm
- Ø 311 mm
Electronics and control
The piezo stages are equipped with open-loop piezo actuators that only require a low-noise driver with an output range of 0 V to 100 V, corresponding to 0 µm to 15 µm of linear motion along the optical axis. For linear-only motion, models with standard LEMO connectors can be directly plugged into a PI piezo driver, such as the E-836. For additional tip/tilt error correction, three independent driver channels are required to control each piezo actuator separately. In this case, models with bare wire strands should be selected to provide individual access to the actuators.
Variants and accessories
- LEMO 1-pole connector for Z motion (LEMO FFA.00.250.CTAC22)
- Pigtails without connector for individual actuator control (Z, tip/tilt)
- Optional cables: P-890 LEMO/solderable end, P-891 extension cables
Application fields
The S-312 piezo stage series is ideally suited for interferometry and other optical circuit applications that require precise incremental motion in the nanometer range. Its piezo actuator and flexure design ensures a lifetime of billions of cycles, with configurations available for both vacuum and cleanroom environments.
