Normally, the Cube is positioned underneath the focus position of the beam path for
power measurement (divergent laser radiation). If this is not possible, the Cube can be
positioned above the focus. Please note that the laser radiation is convergent and the
permitted power density on the absorber (about 25mm under the protective glass) is
not exceeded.
