BWA-CAM for 3D additive manufacturing

3D laser additive manufacturing is becoming an increasingly used method of production and rapid prototyping of products. Whilst this method can produce high-quality components, many processes must comply to standards requiring traceable laser beam measurement before, during and after the process.

The Beam Waist Analyser Camera (BWA-CAM) for 3D additive manufacturing, enables ‘real-time’ laser measurement with no moving parts. The system enables the analysis and monitoring of high-power CW and pulsed lasers, measuring a number of laser beam spatial metrics, such as M2, K and BBP values, beam waist size and location, spatial profile, divergence and astigmatism amongst others.

Whilst other systems show a simulated outside ‘shell’ of the beam, our patented design provides both 2D and 3D profiles of the beam through more than one Rayleigh range. In our system, you always know what your beam looks like and where it is located.
