FTP-2000 Focusing Translation Platform

About the FTP-2000

The FTP-2000 Focusing Translation Platform has been specifically designed to provide a high resolution, and highly repeatable, means of controlling the X, Y and Z position of the stage. The unit is ideal for use with fixed stage microscopes, or any application where ultra precise XYZ positioning is required. 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 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.
