PAGE 262 Premium Line Nano Drives for Research The great success of attocube’s Premium Line positioners is based on the unique combination of a patented driving technology, the powerful design, the selection of high quality materials, and the long experience of the attocube staff. Premium Line positioners allow for reliable motion over centimeter ranges with the highest precision under extreme envi- ronmental conditions such as cryogenic temperatures, high magnetic fields, and ultra high vacuum. Extreme The Premium Line portfolio comprises linear, rotary, and goniometric positioners and scanners – many of them with integrated position sen- sors for closed loop operation. Depending on the requirements, different sizes, travel ranges, and encoder options are available. The innovative design enables the assembling of several stages to positioning units with up to six degrees of freedom. Extreme Environments Large Travel Ranges in Extreme Environments The non-magnetic Premium Line nano drives meet the challenge of nanoprecise positioning systems working reliable under ex- treme environmental conditions. Suitable models are available for cryogenic temperatures, high and ultra high vacuum, as well as high magnetic fields. Positioners of the Premium Line take advantage of attocube‘s patented inertial drive technology which is dedicated for the use in extreme working environments. Controllable motion over cen- timeter ranges with small and reproducible steps of a few tens of nanometers can also be achieved in cryogenic environments, where PZT piezo ceramics are usually limited to scanning ranges of only a few microns. Closed Loop Control Multi Axis Operation Exact and repeatable positioning in absolute and relative terms is an easy task for all Premium Line positioners with implement- ed encoders. Depending on the positioner type and model, up to Closed Loop two Control different encoder options are available: a resistive encoder optimized for cryogenic applications and an optoelectronic en- coder adjusted for applications at ambient temperatures. Z attocube‘s Premium Line positioners are available in a large Y variety of designs, sizes, and travel ranges. They can be stacked X directly on top of each other thus offering highest flexibility for Multi Axis multi-axis operation.
