Controllers: High Speed, Digital Control
A variety of ultra-low-noise 32-bit digital controllers provide fast communications and come with a wide selection of software tools.
Record Travel Range of 1000 µm, Yet Very Stiff and Precise
The long travel range is achieved with a newly designed, friction-free and extremely stiff flexure system, which also offers rapid response and excellent guiding accuracy with trajectory precision in the low-nanometer range. High acceleration forces are provided by multiple, newly-developed high-force multilayer piezo stack actuators.
Features & Advantages
o 1000 µm XY-Travel Allows Probing Larger Areas
o Closed-Loop Digital Control for Up to 99.98 % Position Accuracy
o Stiff and Compact Design for High Resonant Frequencies and Easy Integration
o Resolution <1 nm
o Frictionless, Maintenance-Free Precision Flexure Guiding System
o Ceramic-Encapsulated Piezo Drives for Humidity Protection
o Capacitive Direct-Metrology Sensors for Faster Servo Response
Maintenance-Free, No Wear & Tear
Because flexure-guides, actuators and sensors are all frictionless and maintenance-free, these nanopositioning systems achieve outstanding levels of reliability. The integrated multilayer piezo drives are protected against humidity by a patented ceramic-encapsulation.
Higher Linearity Through Direct-Motion Metrology with Capacitive Sensors
The stages are equipped with non-contact capacitive-sensors and provide motion linearity to 0.02% with effective resolution in the sub-nanometer range. PI capacitive sensors are absolute-measuring, direct-metrology devices that boast very high bandwidth and exhibit no periodic errors.
