The FBP’s are based on a multi-stage high-performance attenuator. An additional 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.
The optical design allows for broadband use and covers all main wavelengths in material processing e.g. in service and maintenance of 3d metal printers, in the automotive industry, as well as in display and semiconductor applications.
