NORTH LOGAN, Utah, Dec. 1, 2015 — Ophir Photonics has announced the latest version of BeamWatch, a noncontact beam monitoring system for high-power YAG, fiber and diode lasers in the 980- to 1080-nm range used in industrial materials processing. The system provides 3D views of laser beam caustic and ellipticity. It charts all beam measurements over time, allowing users to trace waist width and location during setup to more easily determine beam alignment and focus. High-power laser users can monitor how beam characteristics change as the laser is used over long periods. High-magnification optics dynamically measure beams with spot sizes down to 55 μm, allowing for instant readings and rapid correction of large-area cosine changes, resulting in smaller, higher-accuracy welds and cuts with reduced variability across parts.
