7.4
Align the BeamMonitor BM+
For the BeamMonitor BM+, the beam must enter vertically to the x-y-plane.
The laser beam must hit the inlet aperture in the middle.
DANGER
Serious eye or skin injury due to laser radiation
If the ratio of the laser beam diameter to the aperture diameter is too large, increased scat-
tered or directed reflection of the laser beam (laser class 4) will occur during measuring
operation. The housing of the BeamMonitor BM+ can heat up.
X
The laser beam diameter must not exceed 0.7 times the aperture diameter.
X
Especially in case of laser with high beam quality, the laser beam diameter must not exceed
0.6 times the aperture diameter. Otherwise, a falsification of the measuring results due to the
cutting off of border fields is to be expected.
Especially when it comes to the determination of radii according to the second moment
method, measuring errors are otherwise possible.
7.5
Install the BeamMonitor BM+
DANGER
Serious eye or skin injury due to laser radiation
If the device is moved from its calibrated position, increased scattered or directed reflection
of the laser beam occurs during measuring operation (laser class 4).
X
Mount the device so that it cannot be moved by an unintentional knock or cables being
pulled accidentally.
NOTICE
Damage/Destruction of the device
Too long fastening screws can damage internal components in the device.
X
The fastening screws must not be screwed in more than 10 mm into the housing.
There are four threaded holes M6 in the mounting surface of the housing for assembly on a support bracket
provided by the customer (see Fig. 7.3 on page 16 and Fig. 7.4 on page 17).
Please use at least four screws to fasten the device. The total length of the screws depends on the dimen-
sions of the customer’s support bracket. The dimensioned arrangement of the mounting holes is specified in
chapter 16, „Dimensions“, on page 32.
