P-720, P-721 PIFOCÒ Microscope Objective NanoPositioners & Scanners

P-720, P-721 PIFOCÒ Objective NanoScanners

• Remotely Positions Objectives with Sub-nm Resolution
• Travel to 100 mm
• Straightness of Travel £ 30 µrad
• Fast Settling Time

P-720/P-721 PIFOCÒ Microscope Objective NanoPositioners are fast and compact drive units which can be mounted on most microscopes. The units are screwed between the turret and the objective, providing a positioning and scanning range of up to 100 µm with sub-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). Standard thread is W 0.8x1/36", alternate threads are ordered separately. For larger positioning ranges see models P-722 & P-723.

In open loop, the vertical position of the objective roughly corresponds to the drive voltage (see "Tutorial: Piezoelectrics in Positioning" section for behavior of open loop piezos). The open loop models P-720 / P-721.00 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.

Application examples:
Scanning interferometry, surface structure analysis, disk drive testing, autofocus systems, confocal microscopy, bio- technology, semiconductor test equipment.

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 (Electric Discharge Machining) cut flexures are FEA (Finite Element Analysis) modeled for zero stiction/ friction, ultra-high resolution and exceptional guiding precision.
