PZ-2000FT Series Automated Stage with Piezo Z-Axis Top Plate
About the PZ-2000FT
The PZ-2000FT XYZ stage has been specifically designed to provide a high resolution, and highly repeatable, means of controlling the X, Y, and Z position of the microscope stage. The XY axes derive their precise control through the use of closedloop DC servomotors employing high resolution rotary encoders for positioning feedback. By using closed-loop control for stage position, there is not chance that the stage will become lost, as can occur with open-loop microstepped stages after a number of moves and direction changes. The XY stage utilizes crossed roller slides, high precision lead screws, and zero backlash miniature geared DC servomotors for smooth and accurate motion. The top plate of the stage accepts standard K-size slide inserts that are available for any sample, i.e., slides Petri dishes, multi-well plates, etc… The slide insert is moved in the Z-Axis via a piezo element with a range of 150 μm with nanometer accuracy (300 μm & 500 μm range is also available). By moving the sample in the Z-Plane, any objective can be used, eliminating twisting wires or needed spacers as required when a piezo element is put onto a single objective. The microprocessor controlled MS-2000 control unit provides for RS-232 and USB communication with a host computer for control of the XYZ axis.
