The Nano-F Series are piezo nanopositioner focusing elements with 100 or 200 microns of travel. Internal position sensors utilizing proprietary PicoQ® technology provide absolute, repeatable position measurement and for precise closed loop control. Extensive computer modeling (FEA) of the Nano-F Series mechanical structures has resulted in designs with very low off-axis motion (see runout specifications) - which means that microscope images will remain stable throughout the entire range of motion. The Nano-F Series can be used as stand-alone systems or in conjunction with other Mad City Labs nanopositioning stages. Quick mount adapters thread directly into the microscope turret and the nanopositioner can then be clamped onto the adapter without having to rotate the entire assembly with the attached cable. A variety of quick mount adapter threads allow the Nano-F Series to be used on all microscopes. The desired threads on the quick mount adapter are specified for each system when it is ordered. Extra adapters can be ordered separately.
