The Beam Waist Analyser Camera (BWA-CAM) from Haas enables real time laser beam measurement, analysis and monitoring for high power CW and pulsed lasers. For applications such as materials processing; monitoring the laser beam’s spatial profile, circularity, centroid, astigmatism and M2 gives an early warning of any problems with the laser, and entire beam delivery optical system. This can give increased quality process reliability and reduced scrap.
The BWA-CAM is simply placed after the focussing lens of the laser under evaluation and adjusted until the beam waist can be seen. Displaying a number of spatial cross sections along the beam waist, the software automatically tracks and sizes the regions of interest for accurate M2 measurement.
The Beam Waist Analyser Camera is suitable for use with any focal length greater than 100 mm as standard and can be used for focal lengths less than this with an optical focal length adaptor which mounts to the entrance port of the BWA-CAM.
