Sample Scanners

Sample Scanners: High-Speed Z Sample Positioning

Z stack microsections for 3D imaging applications or fluorescence microscopy require high precision and dynamics. Piezo-driven sample scanners usually are 10 to 20 times faster than conventional stepper motors. This allows for more efficient throughput times and higher data acquisition rates. Autofocus and drift compensation functions also work significantly faster.

  • High positioning stability of slides, including well plates
  • Response times within a few milliseconds

  • Minimum offset and excellent focus stability through zero-backlash parallel flexure guiding
