1 Basic safety instructions
Intended Use
The BeamMonitor BM+ has been designed exclusively for measurements carried out in or near the optical
path of high-power lasers. Please observe and adhere to the specifications and limit values given in chapter15, „Technical data“, on page31. Other uses are considered to be improper. The information contained
in this operating manual must be strictly observed to ensure proper use of the device.
Using the device for unspecified use is strictly prohibited by the manufacturer. By usage other than intended
the device can be damaged or destroyed. This poses an increased health hazard up to fatal injuries. When
operating the device, it must be ensured that there are no potential hazards to human health.
The device itself does not emit any laser radiation. During the measurement, however, the laser beam is
guided onto the device which causes reflected radiation (laser class 4). That is why the applying safety regulations are to be observed and necessary protective measures need to be taken.
Observing applicable safety regulations
Please observe valid national and international safety regulations as stipulated in ISO/CEN/TR standards as
well as in the IEC-60825-1 regulation, in ANSI Z 136 “Laser Safety Standards” and ANSI Z 136.1 “Safe Use
of Lasers”, published by the American National Standards Institute, and additional publications, such as the
“Laser Safety Basics”, the “LIA Laser Safety Guide”, the “Guide for the Selection of Laser Eye Protection”
and the “Laser Safety Bulletin”, published by the Laser Institute of America, as well as the “Guide of Control
of Laser Hazards” by ACGIH.
Necessary safety measures
DANGER
Serious eye or skin injury due to laser radiation
Depending on the measuring principle used, the laser beam is reflected at the measuring tip
(laser class4). The reflected beam is usually not visible.
In measurement mode, a safety distance of one meter to the BeamMonitor BM+ must be
X
maintained even when wearing safety goggles and safety clothing.
Please take the following precautions.
X
If people are present within the danger zone of visible or invisible laser radiation, for example near laser
systems that are only partly covered, open beam guidance systems, or laser processing areas, the following
safety measures must be implemented:
• Please wear safety goggles (OD 6) adapted to the power, power density, laser wave length and operat-
ing mode of the laser beam source in use.
• Depending on the laser source, it may be necessary to wear suitable protective clothing or protective
gloves.
• Protect yourself from direct laser radiation, scattered radiation, and beams generated from laser radiation
(by using appropriate shielding walls, for example, or by weakening the radiation to a harmless level).
• Use beam guidance or beam absorber elements that do not emit any hazardous substances when they
come in to contact with laser radiation and that can withstand the beam sufficiently.
• Install safety switches and/or emergency safety mechanisms that enable immediate closure of the laser
shutter.
• Ensure that the device is mounted securely to prevent any movement of the device relative to the beam
axis and thus reduce the risk of scattered radiation. This in the only way to ensure optimum performance
during the measurement.

5 Introduction
5.1 System description
The BeamMonitorBM+ is an opto-mechanical scanning measurement system for analyzing continuous irradiation. The device measures the power density distribution of the raw beam. The LaserDiagnosticsSoftware
LDS uses this to calculate the beam position, beam dimensions, beam symmetry, and power density distribution.
The BeamMonitor BM+ can be mounted in any desired position.
5.2 Measuring principle
The BeamMonitorBM+ is used to analyze the unfocused, continual, high-power laser beam of CO2 or NIR
lasers.
A rotating measuring tip scans the laser beam along the x-axis. During this process, the very small mirror in
the measuring tip separates out a small part of the radiation.
The horizontal carrier moves the measuring tip along the y-axis in order to measure the beam properties of
the laser beam on the x-y-plane. Another mirror finally guides the measurement signal to the detector.

7.4 Align the BeamMonitor BM+
For the BeamMonitorBM+, 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 scattered or directed reflection of the laser beam (laser class 4) will occur during measuring
operation. The housing of the BeamMonitor BM+ can heat up.
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
X
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.

too low.
The signal enhancement is too
low.
1. Please restart the LaserDiagnosticsSoftware LDS .
2. Turn off the supply voltage and turn it on again
and start another reset cycle.
3. Restart the PC.
Please check the device alignment to the laser beam.
The absolute power density typically has to be several
hundred kW/cm² in order to achieve a significant measuring signal.
Increase the resolution in the dialog window Device
control > Single plane > Advanced in the Pixel in
x/y section to something like 1 024 x 1 024 pixels.
Enter the maximum value of 0 dB in the dialog window
Device control > Single plane > Settings in the Gain
in db section.
12 Maintenance and service
The operator is responsible for determining the maintenance intervals for the measuring device.
PRIMES recommends a maintenance interval of 12 months for inspection and validation or calibration.
If the device is used only sporadically, the maintenance interval can also be extended up to 24 months.

17.3 Replace the detector
Generally, the BeamMonitorBM+ is equipped with a DBIG-PS+ or DBC+ detector. Detectors with different
sensitivity or different time behavior can be used for special applications (siehe Tab. 17.1 on page 34).
17.3.1 Remove cover
1. Turn off the power supply.
2. Unscrew four torx screws T8 from the cover.
3. Lift the cover to remove it.
• Under the cover is the detector.

17.3.3 Assemble the detector
Only use isolating plastic screws to fasten the detector to prevent any electric noise signals from
being interspersed. Do not forget the foam rubber spacer during installation, otherwise the rotational disc could be mechanically blocked by the screws. The foam rubber spacer also ensures
mechanical decoupling of the detector.
1. Place the foam rubber spacer(C) on the mounting surface of the detector (see Fig. 17.5 on page 37).
2. Connect the cables.

NOTICE
Blocking the rotational disc
If the screws are tightened too firmly, they might block the rotational disc!
Only tighten the screws hand-tight. The foam rubber spacer must only be compressed to no
X
more than half its original thickness.
3. Fasten the detector with the two plastic screws(D).
