BeamCheck from Ophir Photonics, a beam profiling system that ensures accurate laser performance in additive manufacturing applications of selective laser sintering and selective laser melting.
BeamCheck is an integrated laser measurement system that measures critical beam parameters in laser-based additive manufacturing such as focal spot size, laser power, laser power density at the build plane and changes in spot size and power density over time.
BeamCheck integrates a high-resolution CCD camera for spatial measurements and a NIST-traceable power sensor for a complete analysis of the laser power density profile. The camera is precisely located at the build plane so an accurate power density model of the working laser beam can be made. A beam splitter directs a small percentage of the beam from the fiber laser to the camera while the majority of the beam is directed to the integrated power sensor. From these measurements, an accurate beam spot size and power density can be derived.
