8.3 Align the device
The device must be aligned to the laser beam. The laser beam must hit the inlet aper-
ture in the middle and perpendicular. Please mind and adhere to the specifications and
limit values given in chapter19, „Technical data“, on page50.
Normally, the device is positioned underneath the focus position of the beam path for
power measurement (divergent laser radiation). If this is not possible, the device can be
positioned above the focus.
If the device is mounted above the focus, observe that the laser radiation is convergent
and that the maximum permissible power density on the absorber (approx. 30mm
under the protective window) is not exceeded.
