Technical DescriptionThe Focus Beam Profiler FBP-2KF is a robust and compact analysis system for focused lasers with up to 1kW power. The integrated CMOS sensor with USB3.0 interface enables precise real-time measurements. The FBP-2KF is based on a multi-stage high-performance attenuator. An additional and replaceable filter insert supports optimal adaptation of the attenuation to the respective laser power. The focused laser beam is guided directly to the sensor without imaging optics. Complex corrections of laser power-dependent image errors are no longer necessary. In addition, an absolute power calibration for a specific wavelength is possible. The translation stage enables a fast and reliable measurement of the caustic. | |

Technical DescriptionThe PocketMonitor measures laser power according to the ballistic principle. In this method, an absorber is irradiated with laser radiation for a defined period (10 s/20 s). Based on the warming and the known weight of the absorber after a thermalisation time, the irradiated power can be determined with a resolution lower than 1 W. All information provided by Primes. | |

Technical DescriptionThe FMW+ is an opto-mechanically scanning measuring system that scans the laser beam with a special measuring tip. This is provided with a small hole (typical diameter 20 µm) that lets through a small section of the laser beam. Two reflecting mirrors guide this portion of the laser light to a detector selected and configured depending on the used wavelength. By moving the rotary disk forth the power density distribution of the focused laser is captured at high resolution. The high orbital velocity of the rotating measuring tip facilitates analysis of high power densities. To create a caustic consisting of multiple beam distributions along the propagation, the build platform of the PBF-LB/M machine is used. A very high signal-to-noise ratio is achieved thanks to the dynamics of the used analog-digital-converter. Very low and high intensities can be displayed with equal precsision. This is one of the requirements for measurements of caustics near to the focal point, over at least four Rayleigh lengths (ISO 11146). The FMW+ has been specifically designed to meet the current requirements of additive manufacturing machines. The unit is easy to set up as it requires no external cooling or gas supply. In addition, the user can replace the tip and detector themselves in no time. The special absorber design allows to absorb energy up to 90 kJ. A 400 W laser can therefore be measured for up to 4 minutes at full power. All information provided by Primes. | |
