The BeamWatch® AM from Ophir® is an integrated laser measurement system created for measuring critical laser beam parameters for laser-based additive manufacturing systems. Simultaneous, real-time measurements are performed at video rates and are available for multiple profiles along the beam caustic in the camera field-of-view (FOV). These measurements include waist (focus spot) width and location, focal shift, centroid, M2 or K, divergence, beam parameter product, Rayleigh length, absolute power, and tilt angle measurements.
The real-time performance characteristics of the BeamWatch® AM allows for dynamic focal shift measurements during laser startup. Utilized measurement techniques are based on Rayleigh scattering of laser light, providing an equivalent slit-scan of the laser beam in the direction of the observed view. A CCD camera is included for spatial measurements of the scattered light, and a NIST-traceable power sensor delivers the complete analysis of the laser density profile.
