PI introduces an affordable series of Fast Piezo Nano-Focusing devices at the 2011 SPIE BIOS (Biomedical Optics) meeting in San Francisco, CA.

The new PIFOC® microscopy system packages are designed to improve performance in fast focusing & microscope lens positioning as well in deconvolution / 3D imaging, and reduce costs at the same time.

 

PIFOC® Fast Piezo Focus Systems, 250 µm and 400 µm Travel

Application Examples: Fast Autofocus Systems, Microscopy, 3D Imaging, Screening, Surface analysis, Wafer inspection

The PIFOC® piezo microscope lens nano-focus objective scanner system packages consist of closed-loop piezomechanic objective nanopositioners and custom-tuned compact ditigal servo controller / driver units. This combination provides higher performance at reduced costs. The integrated, frictionless and high-stiffness piezo flexure drive ensures fast response and short settling times, as well as exceptional guiding accuracy. The settling time of less than 10 milliseconds, increases throughput and allows for rapid Z-stack acquisition.

Digital Piezo Motion Controller: more Flexibility, Precision, Automation Functions 
The digital nanopositioning controller provides several advantages compared to the conventional analog motion controllers of the fast nano-focusing systems currently available: higher linearity, improved settling performance, quick adaptation to changing motion requirements and access to advanced automation features

Motion Software, Support, Compatibility with Leading Image Acquisition Programs 
The included motion software facilitates system setup and allows switching of different sets of parameters on-the-fly. For the user this means extracting the maximum resolution and performance from the piezo focusing mechanism all the time, no matter what size microscope objective is used or whether aggressive long-travel stepping or smooth nanometer size dithering motion is needed. Since jumpers and trim pots no longer have to accessed to make changes, system integration becomes much more straightforward.

System setup with the included user-interface software is fast and easy; interfacing to the customers' software is facilitated with the included LabVIEW drivers and DLLs. Drivers for leading image acquisition software packages such as MetaMorph and µManager are available.
