FTP-2000 Fokus Plattform
Die FTP-2000 Fokus Plattform wurde speziell zum präzisen Positionieren der X-, Y- und Z-Achse mit hoher Auflösung und hoher Wiederholgenauigkeit entwickelt. The unit is ideal for use with fixed stage microscopes, or any application where ultra precise XYZ positioning is required. 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 FTP-2000 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.
FTP-2000 Features

- Wide dynamic speed range with XY joystick control
- Utilizes ASI’s proven LS series linear positioners for Z axis control
- Z-axis clutch for easy switching between manual and motor-driven focus control
- Backlit LCD display shows X, Y, and Z coordinates
- “Zero” and “Home” button for simple stand-alone operations
- Compact ergonomic tabletop control unit size is 6”D x 9”W x 3”H (9 x 23 16½ cm)
- Microprocessor control with RS-232 serial and USB communications
- Proven operation with many popular software packages
