This documentation describes the installation and configuration of the ScanFieldMonitor SFM and the execu- tion of measurements with the PRIMES LaserDiagnosticsSoftware LDS. The LaserDiagnosticsSoftware LDS and the plugin for the ScanFieldMonitor SFM must be installed on the PC for measuring operation of the ScanFieldMonitor SFM. The basic version of the LaserDiagnosticsSoftware LDS and the plugin for the ScanFieldMonitor SFM are included in the scope of delivery.
ScanFieldMonitor SFM Important notes on the lithium-ion battery (power bank) A power bank is located on the upper side of the Processing Unit. Two different versions are distinguished: • A Processing Unit with exchangeable power bank. For this Processing Unit the power bank can be pulled out and replaced.
Functional description The measuring system consists of the ScanFieldMonitor SFM and the Processing Unit with power bank. For stable installation of the ScanFieldMonitor SFM on the building platform of the laser system a device holder is supplied. The device holder must be mounted stable in the laser system by the customer and holds the ScanFieldMonitor SFM at the respective measuring position.
To measure the caustics of the laser beam along the beam propagation direction, the ScanFieldMonitor SFM is raised or lowered by the z-axis of the system to be measured. This allows the ScanFieldMonitor SFM to be moved in z-direction and the beam diameter to be measured in different planes. Thus, all important propaga- tion parameters of the entire caustic of the laser beam are obtained: •...

Charge the power bank A power bank is located on the upper side of the Processing Unit.
Setting the output voltage on the power bank The power bank offers the possibility to set the output voltage. The ScanFieldMonitor SFM can be operated with any output voltage of the power bank. However, the power consumption of the Processing Unit is low- est at 12 V output voltage.
3. Put on powder-free latex gloves. 4. Remove the protective window holder carefully upwards. 5. Remove the protective window from the ScanFieldMonitor SFM. We recommend to use a suction cup to remove the protective window. 6. Remove the O-ring from the indentation.
11.2 Installing the protective window spacer 1. Place the protective window spacer on the ScanFieldMonitor SFM. 2. Tighten the protective window spacer with 2 Torx screws M3 x 25 mm (Torx 10 screwdriver). 3. Check for secure fit of the protective window spacer. The protective window spacer must lie flat against the housing of the ScanFieldMonitor SFM.
The ScanFieldMonitor SFM has a square inlet aperture of 20 mm x 20 mm. Within this area the laser radia- tion can enter the device. The scattering structure relevant for measuring amounts approx. 7.5 mm x 7.5 mm.

ScanFieldMonitor SFM. For a secure operation the ScanFieldMonitor SFM may only be operated with a device holder that is able to absorb the exiting laser radiation. If the ScanFieldMonitor SFM is mounted by a customer device holder, it must be ensured that this device holder can absorb the emitted laser radiation.
USB cable with quick-charge plug-in power supply. This is plugged into the USB con- nection socket of the processing unit with the power bank. Please note that the connected ScanFieldMonitor SFM is switched off when the USB cable is pulled out of the USB connection socket of the Processing Unit.
NOTICE Destruction of the network infrastructure If the Processing Unit with ScanFieldMonitor SFM is directly connected to a network via Ethernet, the SFM DHCP protocol randomly assigns IP addresses in the network. Thus, even with a short plugging in of the Ethernet cable, the infrastructure of the network can be dam- aged/destroyed.

The LaserDiagnosticsSoftware LDS uses the Gaussian fit method for radius determination by default. Gaussian fit method The measuring signal of the ScanFieldMonitor SFM consists of the time track of the photodiode. The charac- teristic six peaks are generated when the laser passes over the lines of the scattering structure. This means that a one-dimensional integrated measurement signal is generated.
