DMi-2500 XY Flat-Top Extended Travel Stage
About the DMi-2500 XY Flat-Top Extended Travel Stage
The DMi-2500 Stage has been designed to fit the Leica DMi8 and DMi6000. It is a low profile flat top designed with 250 mm of X-Axis and 110 mm Y-Axis travel (Microscope Limited). The DMi-2500 stage accepts either 160×110 or 283×110 stages inserts. This System has high resolution, high repeatability, and precise motion. Through the use of closed-loop DC servo motors employing high-resolution rotary encoders for positioning feedback, the DMi-2500 has the ability to uses three of the major linear encoder manufactures to improve repeatability to less than 300 nm (typical) compared to the standards rotary encoders 200 nm (typical) repeatability rating.
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 DMi-2500 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.
