Nano-Focusing Device

The P-721.CLQ PIFOC® Nano-Focus Device, for applications such as scanning microscopy and cell tracking, can be mounted between the turret and objective of any microscope for fast and accurate focus control. Direct-measuring, two-plate capacitve position sensors measure the position of the moving part, rather than the strain of the flexures or actuator. This technique, combined with the inherent precision of the non-contact capacitive sensor and the temperature compensated design, results in high linearity scans and superior responsiveness, resolution, repeatability and stability at the nanometer scale. The result is better image fidelity. PIFOCs feature long-base, frictionless, FEA-modeled flexures for exceptional guiding precision. A new QuickLock system allows mounting the unit to the turret in a matter of seconds. A variety of thread inserts are available to adapt the units to any microscope or objective.
