Nanopositioning Stage from PI
Nanopositioning stage.
Auburn, MA — PI (Physik Instrumente) has extended its line of piezo stages for scanning microscopy applications. The P-737 Piezo Z-Focusing Stage is offered along with the stiffer, P-726 high performance microscope lens focusing system for large NA microscope objectives and the redesigned P-686 XY piezo motor positioning stage providing long travel ranges to 25 x 25mm.

The M-686 XY coarse-positioning stage can also accommodate an XY/Z nanopositioning scanning piezo stage to provide the resolution required in single molecule or near field microscopy. Its ultrasonic piezo motors are self-locking and hold a position precisely even when powered down.

The P-726 microscopy objective nanopositioning device provides significantly higher stiffness than other microscope focusing devices due to larger cross section piezo ceramics and a redesigned flexure guiding system. Because of the stiffness, the system can respond and settle faster to provide the highest possible throughput in focusing and imaging applications.

The P-737 specimen Z-stage was specifically designed for biotech research microscopes utilizing deconvolution and 3D imaging techniques. It provides up to 500µm travel, millisecond responsiveness and nanometer precise motion under closed-loop control.

Applications include 3D imaging, Z-stack acquisition, autofocusing, scanning and alignment tasks in microscopy, biotechnology. The P-737 PIFOC® stage is available with a number of analog and highly sophisticated digital piezo controllers and can be controlled through digital interfaces as well as by fast analog signals through a high-speed 0-10V input. The system is fully compatible with all leading imaging acquisition packages. For ease of integration, a comprehensive set of LabView drivers is included, even with the analog control option.

The stage offers a choice of travel ranges: 100µm or 250µm standard, or 500µm on request. The stage has a choice of controllers: digital, analog with display or compact controller; it provides custom tuning for highest speed (few milliseconds per step); is compatible with all major image acquisition packages; is closed-loop for nanometer precise motion control.
