Despite the increased travel ranges the units are extremely compact, while providing sub-nanometer resolution. The long travel range is achieved with a newly designed, friction-free and extremely stiff flexure system which also offers excellent guiding accuracy (typically less than 5 µrad pitch/yaw over the full travel range) and rapid settling. Superior Accuracy Through Direct-Motion-Metrology Capacitive Feedback Sensors Applications such as optical path control in interferometry, or sample positioning in microscopy require long travel ranges with nanometer positioning accuracy. PIHera® offers travel ranges to 500 µm. The closed-loop versions are equipped with non contact, zero friction, direct-measuring two-plate capacitve position sensors. Unlike conventional indirect sensors (such as strain gauge / piezo resistive sensors), they measure the position directly rather than the strain in the actuator / guiding system. Capacitive sensors are absolute-measuring high-bandwidth devices and show none of the periodic errors found in incremental encoders. This permits motion linearity of better than 0.01 % and effective resolution in the sub-nanometer range. This technique, combined with the inherent precision of the PI two-plate capacitive sensor and the temperature-compensated design, results in higher linearity scans, and provides superior responsiveness, resolution, repeatability and stability. Rapid Positioning over Long Ranges One of the advantages of PIHera® stages over (linear) motor driven positioning stages is the rapid response to motion inputs and fast and precise settling behavior. The P-622, for example, can settle to an accuracy of 10 nm in only 30 msec after a 10 mm step (other PI stages provide even faster response)! Dynamic Digital Control for Best Scanning Linearity Use our new E-710 digital control electronics with adaptive dynamic digital linearization (DDL) algorithms for the highest linearity in scanning applications. These systems virtually eliminate tracking errors and permit use of the entire travel range with high dynamic accuracy in the nanometer range. Increased Lifetime with New Piezoceramic Technology The PIHera® stage drive units are based on our P-885 PICMA® low-voltage multilayer piezo ceramics. These newly designed and highly optimized drives are more robust than conventional piezo actuators, and feature superior lifetime in dynamic and static applications. Because guidance and sensors are all frictionless and maintenance-free, PIHera® systems achieve exceptional levels of reliability.
