WESSLING, Germany, May 12, 2010 — Raylase AG has launched the RazorScan-AC laser beam deflection unit that comprises a galvanometer scanner, integrated digital autocalibration devices and autocalibration software. The precision two-axis subsystem guarantees long-term stability, and offset and gain errors are compensated in seconds. The twin-shell design allows ambient temperatures of up to 40 °C. The autocalibration feature ensures that gain drift and offset drift are corrected in seconds. The proprietary calibration software can be used by weldMark 2.0 and by customer-specific software solutions. The system combines exact verification of coordinates, control of deflection with µrad precision and autocalibration. The aluminum twin-shell construction ensures that generated heat is distributed across the entire deflector head, almost completely eliminating temperature gradients. Optimized temperature management ensures that the whole module maintains temperature equilibrium. Available with apertures of 10, 12, 14 and 20 mm, the system is suitable for accurate materials processing such as rapid tooling, deep engraving, edge isolation and trimming, and for applications in which the position of the focused laser beam in the field must remain constant for a long period and must not drift.
