For Microscope Automation
AUBURN, Mass., Nov. 7, 2007 -- PI (Physik Instrumente) LP has introduced the P-737 PIFOC piezo Z-stage, a high-performance nanopositioning Z control system.

The P-737 specimen Z-stage is a new entry in a large line of products for microscope automation. Specifically designed for biotech research microscopes utilizing deconvolution and 3-D imaging techniques, the P-737 PIFOC specimen Z-stage features up to 250-µm travel, millisecond responsiveness and nanometer precise motion under closed-loop control. Applications for the P-737 also include Z-stack acquisition, autofocusing, and scanning and alignment tasks in microscopy and biotechnology.

PhysikInstrumenteP-737.jpgThe P-737 PIFOC stage is an addition to the PIFOC brand of high-speed piezo objective Z-steppers. While no sample stage can beat the speed of the fastest 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 throughput, according to PI.

The fast response of the P-737 fully utilizes the high throughput of the latest digital imaging systems and achieves 10 to 50 times faster response than conventional stepper-motor focus drives, PI said.

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 0-10 V 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 for the analog control option, the company said.

Features & Advantages:
  • Choice of Travel Ranges: 100 µm or 250 µm
  • Choice of Controllers: Digital, Analog w/ Display or Compact Controller
  • Custom Tuning for Highest Speed (few Milliseconds per Step)
  • Compatible w/ all Major Image Acquisition Packages
  • Closed-Loop for Nanometer Precise Motion Control

    stepper motor
    A positioning drive that rotates a fraction of a 360° turn when the motor coils are activated, resulting in linear or rotary motion. They are generally one of two types, either variable reluctance or permanent magnet; the characteristics are much the same. Also called stepping motors.
