The units are screwed between the turret and the objective, providing a positioning and scanning range of up to 350 µm with nanometer resolution while extending the optical path by only 13 mm (infinity-corrected microscope required; extension tubes are available to adjust path lengths of other objectives on the turret). The standard thread is W0.8 X 1/36"", for alternate threads see Ordering Information. For smaller positioning ranges see models P-720 & P-721 (see link). Open- & Closed-Loop Models In open-loop operation, the vertical position of the objective is roughly proportional to the drive voltage (see link in the "Tutorial: Piezoelectrics in Positioning" section for behavior of open-loop piezos). The open-loop models P-722.00 / P-723.00 are ideal for tracking applications where the position is controlled by data provided by an external sensor (e.g. optical displacement sensor, a CCD camera, etc.). The closed-loop versions allow for absolute position control, high linearity and repeatability based on an integrated position feedback sensor. A special PIFOC® for moving the complete microscope turret rather than an objective is available on request. Working Principle PIFOC® positioners are equipped with low-voltage piezoelectric drives (0 to 100 V) integrated into a sophisticated flexure guiding system. The force exerted by the piezo drive pushes a flexure parallelogram via an integrated motion amplifier. The wire-EDM-cut flexures are FEA modeled for zero stiction/friction, ultra-high resolution and exceptional guiding precision.
