1.1 Introduction
The NRT series stages are performance positioning stages which are ideally suited
for measurement and inspection applications. The main platform is supported by 4
recirculating ball carrier bearings mounted to precisely aligned linear guide rails. A
backlash free precision lead screw produces smooth translation, directly driven with
a hybrid 2-phase stepper motor capable of 409,600 micro steps per revolution, and
positioning resolutions of less than 100nm when driven by the BSC series of benchtop
controllers. The highly repeatable, Hall effect (magnetic) home detection limit switch
also provides overdriving protection in both forward and reverse directions.
The high quality stepper motor offers excellent dynamic and static torque
performance and the design provides the detailed features required of any true
nanopositioning product.
