Stages and Linear Translators
ASI’s stages and linear translators are specifically designed to provide a high resolution, and highly repeatable, means of controlling position. All axes derive their precise control through the use of closed-loop servomotors with high-resolution rotary encoders (or optional linear encoders) for positioning feedback. The stages utilize crossed-roller slides, a high-precision lead screws, and zero-backlash miniature geared DC servomotors for smooth and accurate motion. The microprocessor-controlled control unit provides for RS-232 and USB communication with a host computer.
