on laser safety and comply with their requirements.
Necessary safety measures
DANGER
Serious eye or skin injury due to laser radiation
The device measures direct laser radiation, but does not emit any radiation itself. However, during
the measurement the laser beam is reflected at the rotating measuring tip. This produces scattered
or directed reflection of the laser beam (laser class 4). The reflected beam is usually not visible.
X
In measurement mode, a safety distance of one meter to the device must be maintained even when
wearing safety goggles and safety clothing.
X
Protect yourself from direct and reflected laser radiation while working with the device by taking the
following measures:
• Never leave the device unattended when taking measurements.
• If the device is moved from its aligned position, increased scattered or directed reflection of the laser
beam occurs during measuring operation. Mount the device in such a way that it cannot be moved by
unintentional bumping or pulling on the cables.
• Install safety switches or emergency safety mechanisms that allow the laser to be switched off immedi-
ately.
• Use suitable beam guidance and beam absorber elements which do not emit any hazardous substances
when irradiated.
• Wear safety goggles OD 6 adapted to the power, power density, laser wavelength and operating mode
of the laser beam source in use.
• Wear suitable protective clothing or protective gloves if necessary.
• If possible, also protect yourself from direct laser radiation and scattered radiation by using separating
protective devices that block or attenuate the radiation.

4 Device description
4.1 Device type overview
There are two types of the BeamMonitor BM+.
BeamMonitor BM+ 60 BeamMonitor BM+ 100S
Fig. 4.1: Device types BM+ 60 and BM+ 100S
4.2 Functional description
The BeamMonitor BM+ is an opto-mechanically scanning measuring system that scans the laser beam with
a special measuring tip. This is equipped with a small pinhole or reflecting mirror that collects a small section
of the laser beam. Another reflecting mirror guides this portion of the laser light to a detector selected and
configured depending on the used wavelength.
By moving the rotary disk forth a power density distribution is created. The high orbital velocity of the rotating
measuring tip facilitates analysis of high power densities. A very high signal-to-noise ratio is achieved thanks
to the dynamics of the analog-digital converter used. Very low intensities are shown with equal precision next
to the high peak intensities.
4.3 Measuring principle
Using the new LaserDiagnosticsSoftware LDS you can set up the BM+ to automatically repeat measure-
ments in a predefined interval. Accumulate unlimited measurements and check how the beam profile or loca-
tion changes over a long time. For the consideration of shorter time intervals the established Linescan can be
used up to a frequency of 25Hz.
With a newly developed algorithm, the automatic recognition and analysis of rectangular beams becomes
quite straightforward. Besides the lateral length, many unique parameters like the azimuth angle, flank steep-
ness, flatness and uniformity are precisely calculated.

4.5 Explanation of the product safety labels
4.5.1 Warning of hand injuries
A potential hazard area for hand injuries and device damage is marked with a symbol on the device.
The measuring tip of the BeamMonitor BM+ rotates at high speed during the measuring operation. Even af-
ter the measurement or switching off the device, the measuring tip will continue to rotate for a certain amount
of time. To avoid hand injury, do not reach into the aperture of the device.
If the rotating measuring tip hits an obstacle, the measuring tip is de-adjusted. In this case, the device must
be sent in for service. Therefore, no objects may get into the aperture.

7 Mounting
7.1 Conditions at the installation site
• The device must not be operated in a condensing atmosphere.
• The ambient air must be free of organic gases.
• Protect the device from splashes of water and dust.
• Operate the device in closed rooms only.
7.2 Installation in the laser system
7.2.1 Prepare mounting
Check the space available before installing the device, especially the required space for the connec-
tion cables. The device must be firmly installed and must be mounted with screws (see chapter 7.2.4 on
page15).
DANGER
Fire and explosion hazards due to scattered or directed laser radiation
When the BeamMonitor BM+ is being operated, the irradiation must be fully absorbed behind the
measurement zone. Fire bricks or other partly-absorbing surfaces are not suitable.
X
Use an adequate absorber. Dependent on the application, PRIMES offers suitable laser power me-
ters, such as the PowerMonitor PM48/100.
7.2.2 Possible mounting positions

Revision 02 EN - 02/2022
7.2.3 Align the device
For the BeamMonitor BM+, a perpendicular beam incidence with respect to the x-y plane must be ensured.
The laser beam should hit the inlet aperture in the center.
DANGER
Serious eye or skin injury due to laser radiation
If the ratio of the laser beam diameter to the inlet aperture is too large, increased scattered or di-
rected reflection of the laser beam (laser class 4) will occur during measuring operation. The hous-
ing of the BeamMonitor BM+ can heat up.
X
The 86% laser beam diameter must not exceed 0.7 times the inlet aperture.
X
Especially in case of laser with high beam quality, the laser beam diameter must not exceed 0.6
times the inlet aperture. Otherwise, a falsification of the measuring results due to the cutting off of
border fields is to be expected.
This can lead to measurement errors, especially when determining the radius using the second mo-
ment method.
7.2.4 Mount the device
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 in a way 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. 7.2 on page16 and Fig. 7.3 on page17).
Please use at least four screws M6 to fasten the device. The total length of the screws depends on the di-
mensions of the customer’s support bracket.
