Revision 01 EN - 06/2022
1 Basic Safety Instructions
Intended Use
The MicroSpotMonitor-Compact is exclusively intended for measurements which are carried out in or nearby
the optical path of lasers with a power range between 10mW and 1kW. Please mind and adhere to the
specifications and limit values given in chapter 19 „Technical Data“ on page 56. Other forms of usage are
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.
In measuring mode, the device’s safety interlock must be connected with the laser control.
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
During the measurement the laser beam is guided on the device, which causes scattered or
directed reflection of the laser beam (laser class 4).
The MicroSpotMonitor cannot be operated in any of the available configurations without tak-
ing the following precautions.
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:
• Connect the device’s safety interlock to the laser control. Check that the safety interlock will switch off
the laser properly in case of error.
• Please wear safety goggles adapted to the power, power density, laser wave length and operating
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.
MicroSpotMonitor-Compact

8Revision 01 EN - 06/2022
• 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.
Employing qualified personnel
The device may only be operated by qualified personnel. The qualified personnel must have been instructed
in the installation and operation of the device and must have a basic understanding of working with high-
power lasers, beam guiding systems and focusing units.
Conversions and modifications
The device must not be modified, neither constructionally nor safety-related, without our explicit permission.
The device must not be opened e.g. to carry out unauthorized repairs. Modifications of any kind will result in
the exclusion of our liability for resulting damages.
Liability disclaimer
The manufacturer and the distributor of the measuring devices do not claim liability for damages or injuries
of any kind resulting from an improper use or handling of the devices or the associated software. Neither the
manufacturer nor the distributor can be held liable by the buyer or the user for damages to people, material
or financial losses due to a direct or indirect use of the measuring devices.

4 Introduction
4.1 Laser Beam Measurement
Laser beams in industrial applications, whether they be CO2, Nd:YAG- diode or fibre lasers, work with invis-
ible beams in the infra-red or near infra-red spectral range (NIR). Hence changes in beam quality or power
cannot be detected visually, and only become evident from the outcome of their application. Under some
circumstances, this results in very expensive rejects being produced.
If the deterioration in quality is not recognised in the manufacturing process, this usually results in the subse-
quent failure of the product in use, with consequences for the manufacturer of rectification, replacement and
loss of image.
This is where PRIMES beam diagnostics devices for measuring beam quality, focusability and laser power
come in. Process monitoring in production with laser beam diagnostics devices by PRIMES enables consis-
tent quality assurance and allows the timely detection and elimination of malfunctions of laser beams.
PRIMES measuring devices allow the reliable recording of current beam parameters, and enable ongoing
documentation of beam properties for quality assurance purposes. This is a requirement that should not be
underestimated in many industrial areas, such as automotive or medical technology.
With PRIMES devices for beam diagnostics, troubleshooting of laser applications is simplified considerably.
The beam intensity profile, beam diameter, beam caustic before and after focusing, and laser power to be
applied are directly measured and analysed. Based on the readings and their evaluation, maintenance and
servicing personnel can work in a targeted way on repair. Loss of time and system downtimes due to “trying
out” possible causes of the problem are effectively avoided.
The same applies to process optimisation and approval of process windows in laser material processing.
Only if the focal position and focal dimension and also the intensity profile of the laser beam are known, can
processes such as laser beam cutting, welding or drilling be adjusted to the particular component geometry,
materials be selected and the breadth of process windows be determined reliably.

5 System Description
The MicroSpotMonitor-Compact (MSM-C) extends the product family of camera-based focus analysis
systems by a modular configurable measuring system which was optimized for the limited installation space
available in micro-production plants. The following parameters are measured:
• Beam diameter
• Power density distribution
The compact device does not have its own movement axes. In connection with the movement system of a
laser processing plant, however, even caustic measurements which are in conformity with the current stan-
dards can be carried out easily. For an integration into the plant control a PROFIBUS interface is additionally
available. Hence, the determined beam parameters of the machine control are directly available for further
processing. OPTIONally, the MSM-C can also be supplied with a 90° deflection unit for an optimization of the
installation situation within the plant.

8 Installation
8.1 Mounting Position and Attachment
WARNING
Danger of injuries due to scattered radiation
If the measuring device is moved from the measured position, this can lead to scattered
radiation during the measuring operation.
When mounting the device please ensure that it cannot be moved by unintended pushes or
by pulling the cables.
Before mounting the device please check the space available, especially the space needed for the connec-
tion cables and -tubes (please see chapter 21 on page 59).
The MSM-C is mounted horizontally and with a lateral beam incidence. By means of the OPTIONal 90° beam
deflection a vertical beam incidence is also possible.
There are two fastening screw threads M5 in the bottom of the housing which are intended for the mounting
on a customer‘s mount (please see Fig. 8.1). We recommend screws of the strength class 8.8 and a tighten-
ing torque of 5N∙m.
With regard to the OPTION PROFIBUS there are four additional tapped holes M5 and two additional dowel
holes (6H7) in the housing cover.
Fig. 8.1: Fastening screw thread in the bottom of the MSM-C
NOTICE
Danger of damage of internal components
Screws which are too long can lead to a damage of the screw-in thread.
Please ensure that the fastening screws do not reach further into the housing than 10 mm.
MicroSpotMonitor-Compact

16 Revision 01 EN - 06/2022
8.2 Adjustment
Due to the depiction features of the objective it is necessary to position the laser beam focus in a certain
distance above the objective. The higher the focus lies above the objective the shorter it is later depicted
behind the objective.
NOTICE
Danger of damage of optical components
The focus has to have a specified distance to the objective. If distance is too small or too
big, optical components could be damaged when it comes to high beam intensities.
Please adjust the distance according to the specifications given in the TCP certificate.
Positioning of the focused laser beam:
The distance between the measuring plane in which the focus is to be positioned before the first measure-
ment depends on the objective selected. In order to be able to adjust the MSM-C more easily beneath the
laser, an OPTIONal TCP calibration is carried out with each objective. By means of the distance given in
the TCP certificate and the marking on the device (reticule), you can position the measuring device with the
required accuracy. The measuring plane distance equals the distance of the measuring plane to the spot on
the device which is marked with the reticule.
