Press Release from Applied Scientific Instrumentation (ASI)Flat-Top and Extended Travel Stages ASI offers an assortment of stages with flat tops and extended range-of-travel for robotic loading. The MS-2500 stage provides 100 mm of Y-axis travel and 250 mm of X-axis travel, and works very well on existing inverted microscopes. Custom OEM configurations are available including front-loading stages with over 300 mm of Y-axis travel. All axes derive their precise control through the use of closed-loop DC servomotors employing high-resolution encoders for positioning feedback. The XY stage utilizes crossed-roller slides, precision lead-screws, and zero-backlash miniature geared DC servomotors for smooth and accurate motion. ASI stages come standard with rotary encoders with a resolution of 100 nm and bidirectional repeatability better than 800 nm rms. Resolutions down to 20 nm and repeatability accuracies of less 300 nm rms can be obtained with optional linear encoders. Compact table-top and OEM board-level controllers accept industry standard commands, provide automatic backlash correction, and allow RS-232 and USB communication with a host computer.
