Nanometer adjustment precision, wear-free operation, and clean-room compatibility is vital in purposes equivalent to super-resolution microscopy, micro-assembly, beam supply, photonics, and optical metrology, typically requiring steady 24/7 operation. To deal with these wants, PI, a world chief in precision movement management and nanopositioningbroadcasts quick supply of its PIHera collection of XY piezo flexure nanopositioners with XY journey ranges spanning 50 µm to 1500 µm. The PIHera household, contains over 60 compact X, Z, and XY nanopositioning phases with absolute-measuring nano-precision capacitive sensors for excessive linearity and repeatability of movement.
Vibration-Free Movement, Extremely-Excessive-Decision Efficiency, Quick Response
In comparison with conventional motorized techniques that depend on mechanical bearings, flexure-guided piezo positioning phases provide a number of key advantages: they supply wear-free movement with out vibration, obtain nearly limitless decision, and reply rapidly. The design, which excludes rolling components, eliminates bearing rumble, thus making certain the uniformity and straightness/flatness of motion. PIHera precision closed-loop XY phases incorporate absolute-measuring direct-metrology capacitance sensors, enabling resolutions right down to 0.1 nanometers. These phases function a compact design optimized by way of FEA (Finite Factor Evaluation) for prime stiffness and prolonged operational life. Direct metrology provides larger stability and linearity than inferred metrology suggestions with strain-based sensors. The fee-effective nature, solely 0.02% deviation from good linearity, and non-obligatory vacuum compatibility make these compact phases well-suited for purposes demanding frictionless, vibration-free, and extremely correct positioning.
Examined in Area, Trusted on Earth
Powered by PI’s proprietary PICMA® multilayer piezo stacks – examined by NASA/JPL for 100 billion cycles and used on the Mars Rover – PIHera piezo phases provide distinctive benefits for long-term industrial and analysis purposes, together with a large temperature tolerance from -20 °C to 80 °C.
Digital Movement Controller
PIHera phases may be operated with the E-727 piezo controller that provides superior movement management capabilities tailor-made for high-precision nanopositioning purposes. Designed with digital servo management and 24-bit decision, it allows sub-nanometer positioning accuracy and dynamic efficiency. Its built-in notch filters, and automated parameter optimization guarantee superior stability and responsiveness, even in demanding high-throughput purposes. The E-727 helps a number of interfaces — together with USB, Ethernet, and SPI — for seamless system integration, and it’s appropriate with a spread of capacitive, pressure gauge, and piezoresistive sensors.
