MS-4400 XY Scanningtisch

The MS-4400 XY provides a high resolution and highly repeatable means of controlling the X, Y 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. Seine hohe Auflösung und ausgezeichnete Wiederholgenauigkeit über den gesamten Verfahrbereich erhält der Tisch u.a. durch präzise Closed-Loop DC Servomotoren mit integrierten hochauflösenden rotatorischen Encodern zur Positionsrückmeldung. Die Closed-Loop Steuerung schließt ein Verlust der Tischposition aus, wie es nach einer Anzahl Bewegungszyklen bei herkömmlichen Open-Loop Mikroschritt-Tischen der Fall sein kann. 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.
