BeamWatch® AM

 
Description: 

BeamWatch AM is an integrated laser measurement system designed to measure critical laser beam parameters for laser-based additive manufacturing systems.
 
BeamWatch AM provides simultaneous measurements of multiple profiles along the beam caustic in the camera field-of-view (FOV). Real-time measurements are performed at video rates. They include:

  • waist (focus spot) width and location
  • focal shift
  • centroid
  • M2 or K
  • divergence
  • Beam Parameter Product
  • Rayleigh length
  • absolute power

Real-time performance also allows for measurement of dynamic focal shift during laser startup. BeamWatch AM measurement technique is based on Rayleigh scattering of laser light by oxygen and nitrogen molecules in the air as the beam propagates through the medium. Measurement of this scattered light provides an equivalent slit-scan of the laser beam in the direction of the observed view. The scattered light is measured using a conventional CCD camera and image capture systems. BeamWatch AM includes a CCD camera for spatial measurements and a NIST-traceable power sensor that will provide a complete analysis of the laser power density profile.
 
The camera is simultaneously, and real-time, viewing the beam caustic including the near/focus/and far field of the beam. This measurement technique includes Propagation and M2 measurements adhering to the ISO 11146 standards. In addition, and because all measurements are made in real-time, any focal shift occurring during the critical start up seconds is measured and reported.
