ASI - PZ-2000FT Series XYZ Automated Stage with Piezo Z-Axis Top Plate

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 closed-loop 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 and 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 axes.

PZ-2000FT Options

• XY axes Linear Encoders for high-accuracy positioning. Linear encoder resolution is 10 nm, with a scale accuracy of 0.3 μm per 10 mm and 3 μm per 100 mm. Positioning resolution at sample is < 50 nm.
• Auto Focus (requires NTSC or PAL composite video signal).
• ASI’s proven line of Z-axis drives can also be added to the fine focus shaft of the microscope to provide Z-axis positioning with a resolution of 50 nm throughout the range of the microscope’s travel. The piezo unit can then be used for fast and accurate Z-axis positioning to any point within the range of travel.
• Other lead screw pitches are available for faster XY translation, or for more precise positioning when using standard rotary encoders.
