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 25x25 mm.
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
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. Due to the high 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 features up to 500 µm travel, millisecond responsiveness
and nanometer precise motion under closed-loop control
3D imaging, Z-stack acquisition, autofocusing, scanning and alignment
tasks in microscopy, biotechnology.
Piezo Z-Stages and Objective
The P-737 PIFOC stage complements the PIFOC®
high-speed piezo objective Z-steppers. While no sample stage
can move faster than the latest generation of PIFOC® objective
positioners (due to the stiffer, more compact design), the P-737
PIFOC® stage allows for millisecond sample settling enabling
convenient Z-stack imaging with multiple objectives and very high
Piezo Z-Stages vs.
Conventional Stepper Motor Focus Drives
The fast response of the P-737 fully utilizes the high
throughput of the latest digital imaging systems and achieves several
10 times faster response than conventional stepper motor focus drives
and don’t exhibit wear and tear.
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.
