1 Basic safety notes
Intended use
The device has been designed exclusively for measurements in the beam of high-power lasers.
Use for any other purpose is considered as not intended and is strictly prohibited. Furthermore, intended use
requires that all information, instructions, safety notes and warning messages in this operating manual are
observed. The specifications given in chapter17 „Technical Data“ on page85 apply. Any given limit values
must be complied with.
If not used as intended, the device or the system in which the device is installed can be damaged or
destroyed. In addition, there is an increased risk to health and life. Only use the device in such a way that
there is no risk of injury.
This operating manual is an integral part of the device and must be kept in the immediate vicinity of the place
of use, accessible to personnel at all times.
Every person who is responsible for the installation, start-up or operation of the device must have read and
understood the operating manual and, in particular, the safety instructions.
If you still have questions after reading this operating manual, please contact PRIMES or your supplier for
your own safety.
Observing applicable safety regulations
Observe the safety-relevant laws, guidelines, standards and regulations in the current editions published by
the state, standardization organizations, professional associations, etc. In particular, observe the regulations
on laser safety as well as machine safety and comply with their requirements.
Before commissioning, it must be ensured that the entire machine in which the device is installed meets
these safety requirements. Otherwise the commissioning of the device is prohibited.
Necessary safety measures
The device measures direct laser radiation, but does not emit any radiation itself. However, during the mea-
surement the laser beam is directed at the device. This produces scattered or directed reflection of the laser
beam (laser class 4). The reflected beam is usually not visible.
Protect yourself from direct and reflected laser radiation while working with the device by taking the following
measures:
• Wear safety goggles 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.
• 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 unin-
tentionally, i.e. by bumping or pulling 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.
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.

3 About this operating manual
This manual describes working with the FocusParameterMonitor FPM and its settings both
• via a system using a PLC
• as well as with the LaserDiagnosticsSoftware LDS 2.98.
The FocusParameterMonitor FPM is intended to be used with a PLC for fully automated operation. Manual
operation with a PC is not recommended.
However, since the FocusParameterMonitor FPM is designed for measuring short-term exposure and does
not automatically adjust the exposure time, the appropriate exposure time must be determined for the
various beam configurations. The LaserDiagnosticsSoftware LDS 2.98 can be used for setup.
The LaserDiagnosticsSoftware LDS 2.98 is available free of charge on the PRIMES website at:
https://www.primes.de/de/support/downloads/software.html.
In these operating manual, the abbreviations FPM and LDS will be used in the following.

4.2 Functional description
The FPM is designed for laser beam measurement. The beam quality is controlled by means of periodic
measurements which ensures the process quality. The following parameters are measured:
• Laser power
• Power density distribution
• Beam position and beam geometry
• Caustic of laser beams
The FPM consists of three main components: the power measuring unit, the beam analysis unit and the
PROFIBUS®or PROFINET®interface. These components are included in a stable aluminium housing.
An electrically operated shutter protects the beam entrance from pollution.
In addition, an exchangeable protective window is integrated. It is constantly surrounded by compressed air.
The compressed air is required to create an overpressure in the housing, which prevents the penetration of
dirt particles.

4.3 Measuring principle
The device determines the laser power in the power measuring unit according to the calorimetric principle.
For this purpose the absorber of the power measuring unit is irradiated with the laser for a defined time.
Using the known absorber mass and the specific heat capacity of the absorber material, the introduced
energy can be calculated by the measured temperature increase. The measured exposure time can then be
used to calculate the power.
The beam geometry and the power density distribution are measured by the camera-based beam analysis
unit using a CCD sensor. The measurement of beam parameters require an external z-axis.
The measurement data is transmitted to the system control via a PROFIBUS®or PROFINET®interface.
The beam coming from the laser is transmitted through the beam entrance to deflection mirror 1 and from
there to a beam splitter.
The lagest part of the beam enters an absorber which is part of the power measurement unit.
The attenuated beam reaches the beam analysis unit (CCD sensor) via deflecting mirror 2.
The power measuring unit is used to determine the power and the beam analysis unit is used to measure the
beam position and geometry, the caustic and the power density distribution.

6.2.2 Possible mounting positions
The FPM can be mounted both horizontally and vertically. Due to the danger of contamination we recommend
a vertical mounting with a horizontal beam incidence. The plug connections should point downwards and
unused sockets should be covered with the caps supplied.
6.2.3 Align the device
DANGER
Serious eye or skin injury due to laser radiation
If the device is moved from its aligned position, increased scattered or directed reflection of
the laser beam occurs during measuring operation (laser class 4).

Mount the device so that it cannot be moved by an unintended push or a pull on cables.
The device must be aligned to the laser beam. The laser beam must hit the centre of the inlet aperture.
Please mind and adhere to the specifications and limit values given in chapter „17 Technical Data“ on
page 85. The distance between the measurement plane and the entrance plane can be up to 25 mm,
depending on the lens.
The marking on the shutter can be used as an alignment aid. Align the device using the pilot beam with the
shutter closed.
In order to avoid direct reflections into the laser system, the device can be installed offset at an
angle of max. 10mrad to the incoming beam.
