Linear Stage and Driver

Newport Corp. (Irvine, CA) offers the CONEX-AGP controller preconfigured with an Agilis™ AG-LS25-27P linear stage that includes a miniature, built-in, direct-read linear encoder. The stage combines a piezo motor linear stage with the architecture of the CONEX controller family. The controller delivers submicron, bidirectional repeatability of 0.3 μm, making it suitable for applications in confined spaces that require integrated, single-axis control. The linear stage is capable of 27-mm travel and 0.2-μm metal-insulator-metal (MIM).

The controller’s deadband function allows the user to modify the closed-loop parameters to program the acceptable deviation from a position, and to hold that position steady. The controller features the CONEX GUI, accessible via USB. The USB interface also supplies power to the controller, which eliminates the need for additional power supplies and/or cables.
