The M-900KOPS positioning unit from Physik Instrumente (PI) carries out two-dimensional scans quickly and with a high degree of accuracy. External dimensions of 170 mm put this stage in the ‘compact’ league, but it has a 50 mm scanning range in both axes and a load capacity of up to 660 N. A DC direct drive with zero backlash provides a speedy 10 mm/s with 0.1 µm positioning resolution.
The stage has a plain design and is intended for integration, for highly accurate sample positioning in a white-light interferometer or large microscope, for example. PI can match the cover and base plate of the unit individually to the customer-specific installation requirements.
The tried and tested PC plug-in cards of the C-843 controller series and the Mercury™ stand-alone controller are available for a low-cost system combination; they are easy to network and provide a large number of functions for automation applications.
