Giant-aperture, low profile, excessive stiffness – preferrred for optics and interferometry.
Picture Credit score: PI (Physik Instrumente) LP
PI, a world chief in piezo nanopositioning and precision movement management tools, broadcasts the S-312 piezo section shifter stage sequence with 5 aperture diameters starting from Ø2″ (53 mm) to Ø12″ (311 mm). These U.S.-manufactured piezo phases might be mounted horizontally and vertically and are optimized for optical phase-shifting. Their high-stiffness mechanical design helps sub-nanometer steps with millisecond response instances, enabling fast and repeatable fringe shifting in demanding photonics setups.
Options and Advantages
- Piezo stage for horizontally or vertically mounted optics
- 5 Variants with clear apertures from 53 mm (2”) to 311 mm (12”)
- Low profile, from 28 mm for straightforward integration
- Tripod piezo design gives stiff platform and Z and Z-Tip-Tilt movement
- Open-loop, analog voltage pushed for economical management
- 15 µm max displacement at 100 V, ~1.5 µm at 10 V
- Customized variations accessible, i.e. closed-loop and totally different type elements
Operation
The S-312 household of phases characteristic three long-life PICMA® piezo actuators, pushed by an exterior analog amplifier in open-loop operation. The actuators can both be pushed in parallel (piston movement) or individually for Z/Tip/Tilt operation with a 3-channel piezo amplifier. Displacement of every actuator is proportional to the analog drive voltage, permitting for easy integration and management. For instance, a ten V enter sign delivers roughly 10% of the stage’s whole displacement vary at 100 V.
Customized section shifter configurations can be found with closed-loop management utilizing built-in place sensors, together with a wide range of type elements to suit distinctive system necessities. A 0.5-meter cable is normal, supplied with each connectorized and pigtail choices to maximise configuration flexibility.
Controller
PI’s compact E-836 piezo amplifier optimizes the S-312 phases efficiency as an economical, low-noise module with a achieve issue of 10 and an output voltage vary from –30 V to +130 V. Whereas delivering stability and responsiveness, this amplifier options short-circuit safety together with full overcurrent and overtemperature safeguards, guaranteeing dependable, long-term operation even underneath difficult situations.
