1 About this documentation
This documentation describes the special version „FocusMonitor FMW+“ of the PRIMES measuring device
“FocusMonitor FM+” and presents the differences. It supplements the standard operating manual of the
FocusMonitor FM+.
IMPORTANT!
Please pay special attention to the safety instructions given in the standard operating manual of the
FocusMonitor FM+.
2 Distinguishing features in comparison with the standard device
• The FocusMonitor FMW+ does not have an integrated z-axis. For the measurement the focus is moved
along the axis by the system. Information regarding the z-position can either be entered manually via the
settings dialogue (measurement >> single measurement) in the LaserDiagnosticsSoftware.
• An absorber is integrated into the measuring device (maximum absorber power of 1000 watts).
• The maximum energy per measurement is 90kJ (max. irradiation time=90s at 1000Watt).
• The measuring device does not have a protective gas connection
• Direct connection to the PC via Ethernet.

5.1 Inserting the measuring tip
To prevent transport damage, the measuring tip is disassembled when delivered. It is to be installed with the
curved part facing towards the beam source.
There are different measurement tips available for different wavelengths (see Tab. 5.2 on page6).
NOTICE
Danger of damaging the measuring tip
The small drill hole in the measuring tip can be blocked easily by dirt particles or by
touching it with bare hands.
When mounting/dismounting the tip, please wear powder-free latex gloves and ensure a
dirt- and dust-free environment.
1. Turn off the supply voltage.
2. Turn the drive wheel (see Fig. 5.4) clockwise until the disc extends approx. 15mm into the measuring
window in a positive y-direction.
Drive wheel
Disc with measuring tip retaner
Fig. 5.1: Moving the disc into the measuring window
3. Turn the disc until the measuring tip retainer becomes visible in the opening of the housing.
4. Remove the fastening screws (Torx T8) as well as the retaining plate.
5. Carefully insert the new measuring tip in the disc (caution, the entrance aperture is located on the arched
side of the tip, see Fig. 5.2).

6 Notes on the absorber
The high-power absorber can absorb an energy application of 90 kJ (1000 W · 90 s).
NOTICE
Risk of damage caused by overheating
The absorber is equipped with an alarm siren that warns of overheating. It activates when
the absorber casing reaches a temperature of 60 °C.
In case of alarm, immediately turn off the laser and allow the absorber to cool!
NOTICE
Risk of burns
The laser beam can make the surface of the absorber very hot.
Do not touch the absorber during or immediately after a measurement!
7 Mounting/Dismounting
7.1 Installation position
The FMW+ was designed for a vertical beam incidence from above.
7.2 Alignment
1. When positioning the device in x- and y- direction,
please make sure that the laser beam hits the

There are different measurement tips available for different wavelengths (see „Tab. 5.2: Variety of measurement tips and detectors“ on page6).
NOTICE
Danger of damaging the measuring tip
The small drill hole in the measuring tip can be blocked easily by dirt particles or by touching it with bare hands.
When mounting/dismounting the tip, please wear powder-free latex gloves and ensure a
dirt- and dust-free environment.

13.2 Exchanging the detector
The NIR detector is the standard detector of the FMW+. For measurements with a CO2 laser the detector
has to be replaced by a CO2 detector.
NOTICE
Danger of damage for the detector sensor
The detector sensor must not be damaged and has to be protected from pollution.
Do not touch the detector sensor with your fingers and do not put it down on the sensor
surface.
Only use insulating plastic screws to fasten the detector to prevent noise signals. Do not forget the
foam rubber plate, otherwise the disc may be mechanically blocked by the screws.
Mounting sequence:
1. Turn off the supply voltage
2. Turn the drive wheel anti-clockwise as long as
possible. Now the detector is in its dismounting
position.
3. Carefully remove the two plugs from the detector,
for example by means of long nose pliers.
