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 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. 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 utilising deconvolution and 3D imaging techniques, It features up to 500µm travel, millisecond responsiveness and nanometer precise motion under closed-loop control
