PZ-2000 XYZ Series Automated Stage with Piezo Z-Axis Top Plate
About the PZ-2000XYZ
The PZ-2000 XY stage has been designed to provide a high resolution, and highly repeatable, means of controlling the X-, Y-, and Z-position of the microscope stage. The X- and Y-axes derive their precise control through the use of closed-loop DC servo motors that ensure the travel range of 120 mm x 110 mm and employ high-resolution rotary encoders for positioning feedback. By using closed-loop control for the stage position, there is no chance that the stage will become lost, as can occur with open-loop micro-stepped 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 servo motors 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 along Z-axis, 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 X-, Y-, and Z-axes.
PZ-2000 XYZ Features
- Closed-loop control of the X-, Y-, and Z-axes for precise positioning and highly repeatable focusing
- Wide dynamic speed range with adjustable trapezoidal move profiles
- Smooth adjustable dual-range joystick control.
- Proven operation with many software packages.
- Travel range will scan full well plate in most circumstances.
XY Specifications for Standard Configuration
PZ-2000 XYZ Options
- X- and Y-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.
- Stage wings for even more room for attachments.
