Applied Scientific Instrumentation offers an assortment of stages with flat tops and extended range of travel for robotic loading. The MS-2500 provides 100 mm of Y-axis travel and 250 mm of X-axis travel and works well on existing inverted microscopes. Custom OEM configurations are available, including front-loading stages with more than 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 X-Y stage uses crossed-roller slides, precision leadscrews and zero-backlash miniature geared DC servomotors for smooth and accurate motion. The stages come standard with rotary encoders, a resolution of 100 nm and bidirectional repeatability of better than 800 nm rms.
