The Ophir BeamWatch AM is a non-contact laser beam monitoring system for additive manufacturing.
BeamWatch AM is a lightweight, compact system designed for real-time measurement of focal shift during laser startup of powder bed fusion manufacturing processes. It measures key beam size, position and quality parameters, including focus spot size and beam caustic. These measurements allow users to more easily determine when the beam is aligned and in focus, providing more consistent metallurgy. Measurements can be displayed as tabular, 2D and 3D views, providing a quick and realistic display of laser characteristics. System measurements include laser power, waist width, waist location, focal plane location, spot size at focus, spot size at any point along the 10-mm measurement space, ellipticity, Rayleigh length, M2, K, BPP, divergence and centroid beam tilt.
BeamWatch AM uses Rayleigh scatter to image the beam without contacting the laser, removing the potential for damage to the laser and speeding the measurement process by up to two minutes. BeamWatch AM can measure laser powers to 1000 W in situ at rates up to 14 Hz and can handle up to 120,000 J without cooling. Results can be charted and exported to .csv files for importing into Excel or other analysis software.
