The MS-9400 XY motorized stage system has a travel range of 9" by 4" (225 x 100 mm) and has been specifically designed to scan eight 25 x 75 mm slides at a time while providing a high resolution, and highly repeatable, means of controlling the X and Y position of the microscope stage. All axes derive their 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 700 nm rms rating, and improve resolution to 50 nm.
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 microprocessor-controlled MS-2000 Control Unit provides for RS-232 and USB communication with a host computer.
