MS-2500 XY Flat-Top Scanningtisch mit erweitertem Verfahrbereich

Der XY Mikroskoptisch / Scanningtisch MS-2500 verfügt über einen Verfahrbereich von 100 mm in der Y-Achse und 250 mm in der X-Achse. Er wurde frei von Störkonturen und in einem extrem flachen Design konstruiert. Dies und sein erweiterter Verfahrbereich in der X-Achse erlaubt es bei automatisierten Anwendungen eine Beladeposition anzufahren oder Einlegerahmen mit einer größeren Anzahl Proben zu bestücken. The MS-2500 stage series accepts either standard 160 × 110 or wide 283 × 110 stage inserts. Total stage thickness is only 54.1 mm (2.13”), and only 29.3 mm (1.16”) from its flat obstruction-free top to its bottom mounting surface.

The high resolution and highly repeatable stage series derives its precise control through the use of closed-loop DC servomotors employing high-resolution rotary encoders for positioning feedback. Optional linear encoders improve repeatability to less than 300 nm (typical) compared to the standard rotary encoder’s 700 nm (typical) repeatability rating.

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-2500 XY stage series utilizes crossed-roller slides, a high-precision lead screw, and zero-backlash miniature geared DC servomotors for smooth and accurate motion. Complete XYZ motorization is supported by adding a Z-axis drive using ASI’s proven closed-loop control, each Z-drive custom fitted to the specific microscope, Nikon, Leica, or Zeiss. The microprocessor-controlled MS-2000 control unit provides for RS-232 and USB communication with a host computer.
