Extrem stabiler XYZ-Scanningtisch für hochauflösende Mikroskopie

The US-2000 Flat Top XYZ stage has been specifically designed to provide an ultra-stable, high resolution, and highly repeatable means of controlling the X, Y position of the microscope stage for superior resolution microscopy applications. The stage can be used in conjunction with ASI’s proven line of Z-axis motor drives, each custom fitted to the microscope for complete XYZ positioning. All exes derive their precise control through the use of closed loop DC servomotors employing high resolution rotary encoders for positioning feedback. For ultra high precision Z focusing piezos can be embedded within the top plate of the stage in travel ranges of 150, 300, or 500 microns. The US-2000 XY stage utilizes crossed-roller slides, a high precision lead screw, and zero backlash miniature geared DC servomotors for smooth and accurate motion. XY travel ranges from 25mm to 120mm are available. To minimize thermal drift it is best to choose the 25mm travel range as it uses a smaller lead screw to reduce thermal variations at the sample. With the optional linear encoders and 0.635mm pitch lead screws resolutions of 2.5nm with true optical resolutions of 10nm at the sample are available. The micro-processor controlled MS-2000 control unit provides for RS-232 and USB communication with a host computer. Systems are available for all standard research grade microscopes and OEM applications.
