EUTECT’s portable laser power meter for all laser soldering applications

EUTECT’s laser soldering modules are characterized above all by the combination of the air-cooled, cleanroom-manufactured diode laser system in cooperation with the Sensitive Wire Feeder (SWF) from our company. Furthermore, the laser soldering module with a pyrometer-controlled laser power input and the coaxial optics, in which laser, pyrometer and camera are centrally mirrored, offers reliability and high reproducibility. For this reliable, controlled soldering process, the individual process data, such as the laser power, are crucial.

To obtain this data accurately and correctly, it is necessary, among other things, to check the laser power regularly. For this purpose, EUTECT offers a compact measuring system that can be carried along at any time. With this measuring system, the power of the lasers used can be easily monitored. Thus, the power measuring device offered by us can be used for cyclic (semi-annual / annual) control of the lasers. If the diodes have lost too much power over the operating period and need to be replaced, this will be clearly shown by the measurements.

The power meter is easy to operate and ready for use within a few minutes. Data logging is done in its internal memory. After the measurement, it is possible to transfer the data to a PC via the USB connection.
