Nmark AGV galvanometers use innovative optical feedback technology to increase resolution to greater than 24 bits, compared with the 16 or 20 bits achieved by other high-end scanners for laser micromachining applications. When driven by the Nmark CLS galvo controller, AGV series scanners offer advanced application tools to ensure consistent laser spot placement and fast scanner positioning over the entire servo travel area. The result is a significant improvement in accuracy: A 100-mm focal length lens has 2-D positioning accuracies of 10 µm or better.
Aerotech's Nmark AGV-HP advanced galvanometers use innovative optical feedback technology to increase resolution to greater than 24 bits. AGV-HP series scanners may be directly driven by Aerotech's Nmark CLS galvo controller, which offers a full suite of advanced application tools including Position Synchronized Output (PSO) and Infinite Field of View (IFOV).
The IFOV controller feature allows seamless synchronization of galvanometer and servo motion. Long vector moves that would otherwise exceed scanner field of view are enabled by combining servo/scanner motion.
Fast motion with sharp direction reversals is accomplished with high dynamic scanner motion.
Large features (or large combinations of smaller features) may be marked continuously by interleaving scanner and linear motor stage moves.
Direct access to encoder feedback allows real-time laser triggering based on combined AGV (galvo) and stage positions.
Aerotech's PlanarDL is an integrated, low-profile, XY motor stage with superior planar performance. With straightness performance to +/- 0.4 microns and flatness to +/- 1 micron, images taken of profiled surfaces show amazing detail of critical texture and features. Capable of 1 m/s speeds and greater than 1.5 g accelerations.
