PI precision positioning stages and actuators have been used in many noncontacting optical inspection and contacting nanometrology applications. They provide sub-nanometer precision and extremely uniform motion.
PI's capacitive nanometrology sensors measure motion down to the sub-nanometer range with very high bandwidth.
PI piezo actuators can be used to precisely focus a microscope objective in milliseconds, and they can also help to sort cells rapidly.
PI piezo actuators and piezo motors provide very high forces and require little to no power in quasistatic applications. They can also work in a vacuum and at very low temperatures—conditions found in space applications.
PI provides a large variety of fast objective lens positioners (Z-motors), as well as sample scanners for deconvolution and 3D imaging (Z-stack acquisition) and fast focusing stages.
PI offers a wide variety of piezo based solutions from long-life PZT ceramics for vibration cancellation to the ultra-high-performance NEXLINE® long-travel nanopositioning piezo motors.
