ASI MS-4400 XYZ Automated Stage

 

The MS-4400 XYZ provides a high resolution and highly repeatable means of controlling the X, Y, and Z position of the microscope stage. The MS-4400 XY stage has been specifically designed for larger upright microscopes like the Leica DMR-series, the Nikon Eclipse 80i, the Olympus BX series, and the Zeiss Axioplan, Axioskop 2, and Axio Imager. 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-4400 XY stage utilizes crossed-roller slides, a high-precision lead screw, and zero-backlash miniature geared DC servomotors for smooth and accurate motion. The Z-axis drive also uses ASI's proven line of closed-loop motor drives, each custom fitted to the microscope. The microprocessor-controlled MS-2000 control unit provides for RS 232 and USB communication with a host computer.
