Easy-to-Use Laser Beam Analysis for Optimizing AM Processes



MKS Instruments offers Ophir BeamPeek Software for field technicians, an easy-to-use laser beam analysis software for fast, accurate, real-time measurement of lasers in additive manufacturing (AM) chambers. Designed specifically for the needs of field maintenance, the system analyzes the most critical beam parameters for process optimization, including Waist Width, Waist Location, Power Density, M2, Beam Parameter Product (BPP), Ellipticity and Rayleigh Length. Technicians are then provided with a comprehensive view of the beam's shape, size and intensity distribution, facilitating rapid identification of any irregularities or deviations.

"AM chambers present a challenging environment for high power laser-based systems and the field team responsible for optimizing performance," said Reuven Silverman, General Manager, Ophir Photonics. "BeamPeek Software allows users to obtain critical beam measurements in the shortest time possible with little or no user intervention. If desired, they can also enter their own custom measurement locations with ease. The end result is clear and concise data that technicians can trust as it is ISO 11145 and ISO 11146 compliant."

BeamPeek Software provides an easy way to measure laser power and beam caustic simultaneously, without the need for complex analysis. Features include 2D beam display, Caustic display and stacked 3D beam display to represent and visualize beam measurement results. The intuitive interface can be customized to specific user needs. The Results display panel represents key laser parameters: Beam Width, Ellipticity, Z location, X alignment, Y alignment, Total Power and Average Power density for a given frame, as well as Waist Width, Waist Location, Power Density at Waist, M2, BPP and K for the caustic measurements.

For more detailed results and analyses, technicians can load the Results file from BeamPeek Software into Ophir BeamGage Professional software for full post-processing capabilities. BeamGage is an advanced beam analysis system. It is based on Ultracal, Ophir's patented, baseline correction algorithm that helped establish the ISO 11146-3 standard for beam measurement accuracy. BeamGage software includes all the calculations needed to make accurate, ISO approved laser beam measurements, including power and spot diameter, power density, spot position and more. The software provides advanced image processing features, NIST-traceable power measurements, trend charting, data logging, pass/fail production testing and multilingual support.

BeamPeek Software works with Ophir BeamPeek, a compact, ruggedized high-power laser beam analysis and power measurement system for AM. The system provides beam profiling, focal spot analysis and power measurement in just three seconds. There is no need for water or fan cooling as the system includes a replaceable passive cooling beam dump tray that eliminates downtime between measurement sessions. The BeamPeek system is suited for field service testing of AM chamber powder beds. It is able to withstand chamber conditions, including the presence of metal powder residuals and when cooling agents or airflow connection points are not available. The BeamPeek system is supported by a range of Ophir software options: BeamPeek Software, StarLab, BeamPeek Tool, and, for more complex analyses, BeamGage Professional.
