Figure 4-37 Fixed Crosshair Panel
The “Fixed Crosshair Panel” panel activates a new tab on the right-hand side of the user interface. It
contains the settings relative to the fixed crosshair. This tool allows you to easily fix and see the crosshair
at a precise position on the sensor. Please refer to section 07 for more information about this function.
4.6. BEAMAGE-M2 MODE
Figure 4-38 Show/Hide M2 Mode Button
The M2 mode activates the M2 measurement functions of PC-Beamage-3.0 software when using the
Beamage-M2 accessory. For more information on how to use this mode, please refer to the Beamage-M2
manual which can be found in the Help section (refer to 4.7.3).
The M 2 factor can be considered as a quantitative indicator of laser beam quality. In terms of
propagation, it is an indicator of closeness to an ideal Gaussian beam at the same wavelength.
Paired with a Beamage-3.0 beam profiling camera, the Beamage-M2 module can provide Real-
Time M
2 measurement directly in the PC-Beamage-3.0 software. The calculations are based on
the second order spatial moments and therefore are fully compliant to the ISO 11146 and 13694
standards.
Unlike other M
2 measurement systems, the Beamage-M 2 can measure the propagation
parameters of a laser beam without the need of any moving part or an external power supply,
providing calculation of the M
2 factor in less than a second. This condition allows the possibility
to do on-line monitoring. Its modular design allows users who only want to measure the energy
or intensity spatial profile of their beam to remove the Beamage-3.0 from the M
2 module and
use it as a simple beam profiler.
