PZMU-2000 Piezo-Z Top Plate

About the PZMU-2000

The PZMU-2000 is a precise piezo Z-axis stage that can be attached to the top of a microscope’s existing XY stage or be used in stand-alone applications. On select models of microscopes, ASI can mount a PZMU-2000 to an OEM stage. We can procure a manual OEM stage for you if necessary.

The PZMU-2000 consists of ASI’s proven piezo-Z top plate mounted within a stand-alone housing. This system can be mounted to any horizontal surface, including on top of a manual XY stage of an upright microscope.

The optional MS1-PZM Controller compliments the ASI PZMU-2000, providing an LCD readout of position, an external focusing knob, RS-232 serial control, home and zeroing controls all in a small 6 x 4 inch (152 x 102 mm) footprint.

The PZMU-2000 has been specifically designed to provide a high resolution, and highly repeatable, means of controlling the Z position of a manual microscope stage. The XY axes would remain manually controlled by the original OEM stage controls. The PZMU-2000 accepts standard K-size slide inserts that are available for any sample, i.e., slides, Petrie dishes, multi-well plates, etc. The slide insert is moved in the Z-axis via a piezo element with a range of 100 μm and with nanometer accuracy (200 μm and 500 μm ranges are 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 piezo stage can be controlled remotely with a 0-10 volt D.C. analog input voltage, or optionally, with a PZM-2000 Controller.
