MS-2000 Flat-Top XYZ Automated Stage

Home » Products » Stages » Inverted Stages » MS-2000 Flat-Top XYZ Automated Stage

The MS-2000 Flat Top XY stage has been specifically designed to provide a high resolution, and highly repeatable, means of controlling the X, Y position of the microscope stage. 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 X, Y, and Z positioning. All 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 of 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 MS-2000 XY stage utilizes crossed-roller slides, a high-precision lead screw, and zero-backlash miniature geared DC servomotors for smooth and accurate motion. The microprocessor-controlled MS-2000 control unit provides for RS-232 and USB communication with a host computer.
