The PZ-2000 series stages from ASI have 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 encoders for positioning feedback.
The XY stage provides resolutions down to 2.5 nm with repeatability factors down to 20 nm. The top plate of the stage accepts standard K-size slide inserts that are available for nearly any sample.
The slide insert is moved in the Z-axis via piezo elements with ranges of 150 um, 300 um & 500 um available. The piezos utilize strain gauges mounted on the amplifiers to provide close loop control with nanometer accuracy. The piezo control electronics mount within the ASI controller and auto calibrate to provide extremely accurate positioning.
