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 chap-
ter 15, „Technical data“, on page 31. 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 regu-
lations 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 class 4). The reflected beam is usually not visible.
X
In measurement mode, a safety distance of one meter to the BeamMonitor BM+ must be
maintained even when wearing safety goggles and safety clothing.
X
Please take the following precautions.
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.
